Benefits of Carbide Cutting Tools
By: John Morris
In every machining system, one simply can't ignore the important role that cutting tools play. Oftentimes, the quality of a finished product would rely on the quality of the cutting tools. The quality and the performance of cutting tools would also directly affect a machining system's overall productivity. It is because of their importance that manufacturers would take into consideration several criteria before eventually buying a piece of cutting tool for their machining system. Included in these criteria are the tools ability to last long under rigorous operating conditions and their capability to perform at very high speeds. Also important is the tool's resistance to wear and tear, including resistance to breakage, edge and flank wear, cratering or top wear, chipping, built-up edge (BUE), deformation, and thermal cracking.
1. Kinds Of Tools
As the demand for better cutting tools increase, cutting tool suppliers also continuously develop products that can pass manufacturers' demands. Through the years, a lot of materials for the manufacture of cutting tools have been experimented upon; some have passed the standards while others were simply dropped. Today, there are only two types of cutting tools heavily favored in the machining industry: high speed steel (HSS) cutting tools and carbide cutting tools; and it seems that carbide cutting tools have slightly overtaken the other in popularity. So, what advantages do carbide cutting tools have over their HSS counterparts? Considering their lead in popularity, it is clear that the benefits of carbide cutting tools outnumber that of HSS cutting tools. And we'll understand these benefits better if we know what carbide really is.
2. What is Carbide?
In chemistry, carbides refer to any group of compounds made up of carbon and one other element that can be a metal, boron, or silicon. There are actually many compounds belonging to this group, among the more popular of which includes:
- Calcium Carbide
- Aluminum Carbide
- Silicon Carbide
- Tungsten Carbide
- Iron Carbide
3. Industrial Uses of Carbide
In the 20th century, carbides have been used for a lot of industrial applications. Carbides used in industrial applications are often called cemented carbide products and are classified in three major grades:
- Wear grades
Used primarily in dies, machine and tool guides
- Impact grades
Higher shock resistance carbide products used for dies, particularly for stamping and forming
- Cutting tool grades
Carbide tools used for cutting
4. Carbide Cutting Tools
Cutting tool grades of carbides are further subdivided into two groups: cast-iron carbides and steel-grade carbides. As their name implies, cast-iron carbides are specifically made for cutting cast-iron materials. These carbides are more resistant to abrasive wear, protecting the carbide cutting tool from edge wear due to the high abrasiveness of cast-iron. Steel-grade carbides, on the other hand, are specially made to resist cratering and heat deformation that may be caused by the long chips of steel on higher cutting speeds. Whichever grade of carbide is used in a carbide cutting tool, the main carbide material used in its manufacture is tungsten carbide (WC) with a cobalt binder. Tungsten carbide is well known for its hardness and resistance to abrasive wear. Cobalt, on the other hand, is used to further toughen the tool's surface.
5. Other Variants
Aside from tungsten carbide and cobalt, other alloying materials are added in the manufacture of carbide cutting tools. Among them is titanium carbide and tantalum carbide. Titanium carbide helps the carbide cutting tool to resist cratering while tantalum carbide can reduce heat deformations in the tool. Also commonly used in the cutting industry today are coated carbide cutting tools. Aside from the basic carbide materials, titanium carbide, titanium nitride, ceramic coating, diamond coating or titanium carbonitride are used as coating materials. The different coating materials aid the carbide cutting tool differently, although they are generally used to further toughen the cutting tool.
6. Benefits of Carbide Cutting Tools
- Toughness
- Exceptional resistance to abrasion
- Superior wear resistance
- Resistance to cratering
- Resistance to thermal deformations
- High modulus of elasticity
- Chemical inertness
- Torsional strength twice that of HSS
- Compressive strength

Repair, Restore, Remodel: Five Multi-tools That Will Multiply Your Productivity
For renovations, repairs, and restorations craftsmen demand a tool that delivers always professional results. For all these applications, and many more - there exists one tool to champion over all others, the multi-tool. A multi-tool is, as the name indicates, is a tool - one tool - that performs multiple functions. For versatility and functionality a multi-tool is truly unbeatable. The design of most multipurpose tools makes them ideal for tight space applications and close quarter work in corners and on floors. Utilizing oscillation technology, or a rapid, successive back and forth motion, a multi-tool cuts and sands, scrapes and grinds with better handling and precision than any other tool available. This oscillation, not unlike vibration, delivers optimal control, precision, and accuracy in all its applications.
From the company that developed the world's first oscillating MultiMaster over 41 years ago, there are several multipurpose tools available. In 1967 Fein developed the first power tool to utilize this coveted oscillating technology To begin, Fein's MultiMaster Start is a high performance tool designed around beginners and simple home-repairs and restorations. The Start is the first link in Fein's MultiMaser chain (behind the MultiMaster Select and MultiMaster Top), but at no sacrifice to quality, performance, or professionalism. The Start is a true-blue MultiMaster capable of all cutting, grinding, scraping, and sanding applications; and utilizes some of the most advanced accessories for sawing, scraping, and etc. The Start's lightweight and ergonomic design make it simple to use and control, and with a powerful, variable speed (up to 21,000 OPM), 250 watt motor - Fein's Start is both strong and versatile. This superior versatility makes the Start a great tool for simple renovations like flooring, tile work, windows, and cabinets. Fein's Multi-Master Start includes one sanding pad (with hook and loop design for easy changes on the job) and five of each type of sanding sheet in 60, 80, 120, and 180 grain. The start also includes: a key and mounting bolts - a rigid stopping knife for lifting linoleum, carpet, adhesive residue, paint, tape etc. - and a (29mm) universal E-Cut blade for base and flooring work. The E-Cut blade is ideal for door jambs, baseboards, toe kicks, and other flooring applications. It effortlessly cuts through plaster, wood, drywall, and plastic and synthetic materials. The blade has an unique fine tooth pattern for enhanced control, accuracy, and blade life - and a flush cut design that provides perfectly perpendicular cuts for flooring and tight areas.
Fein's MultiMaster Select and Top both offer the features of the Start with a few more benefits. The MultiMaster Select is a professional renovation tool built with Fein's tool-free quickIN rapid clamping system which allows for quick and simple, keyless accessory changes and the same powerful, variable speed motor. The Select includes, in addition, a carbide tipped saw blade and an HSS segmented saw blade. The carbide blade is is essential in removing damaged tile joints and carving grooves in plaster, concrete, and other similar building materials. The flat, high-speed segmented blade is designed for cutting hardwoods and other hard materials like carbon-fiber, fiber-glass, and 20 gauge sheet metal. The blade's segmented shape allows it to cut right, or ninety degree angles without over-cutting. Now, the MultiMaster Top is designed to help craftsmen professionally complete the most detailed jobs or hobby projects. It includes the same accessories as the Start and Select, and all the additional ones necessary to champion a wide range of applications. The Top includes a perforated sanding pad with 5 more of each grain (60, 80, 120, and 180, perforated), a profile sanding set, dust extraction device, plastic carrying case, and a triangular, perforated, carbide rasp for grinding filler, adhesive, concrete, stone, and wood. Fein's MultiMasters are generally more expensive than their competitors, but, Fein also has the experience, technology, and longevity to provide an exceptional product.
Now, after losing their patent around a year-or-so ago, Fein has some tough competition. Bosch has just released their new Multi-X multifunction tool powered by a professional, high-performance 12v motor. Oscillating from 5,000 - 20,000 OPM, the tool's variable speed dial is designed to provide the huge range of applications and speed adjustments needed for a craftsman's very multifaceted work day. For enhanced versatility and precision, Bosch's Multi-X has multiple position settings rotating in 30 degree increments, and a tool holder with a 240 degree angle adjustment for optimized tool movement. Weighing only 2.12 lbs Bosch's multi-tool has a soft grip, a small perimeter, and a comfortable ergonomic design. This comfortable design reduces operator stress and fatigue, and maximizes overall performance on the job. To protect your projects and materials as you work, Bosch's multi-tool also has a no-mar plastic nose. The Multi-X is powered with Bosch's Litheon battery technology which utilizes lithium ion technology to achieve optimal battery life and power. Litheon batteries are lightweight and compact delivering maximized power in a more effecient package. Bosch has also incorporated a built-in fuel gauge for battery charge control. Capable of countless applications, the Multi-X is ideal for seasoned craftsmen and carpenters, and serious do-it-yourself-ers alike.
The Multi-X is compatible with a huge range of premium performance Bosch accessories including: plunge cuts for both metal and wood, sanding pads, and grout removal and flush cut accessories. An etched depth gauge for accurate capacity measurements, and Bosch's universal interface are also available. The interface makes the Multi-X compatible with accessories and attachments from other manufacturers. The Multi-X is available in two packages: the PS50-2A and PS50-2B. The Multi-X PS50-2A include and HCS wood plunge cut blade, sanding plate set, sanding paper, two Litheon 12v max batteries, an adapter, 30 minute charger, and carrying case for security and convenience. The PS50-2B includes everything from the previous package, with three additional HCS wood plunge cut blades and an HCS wood segment blade. Bosch's Multi-X is versatile, durable, efficient, and backed by Bosch's Provantage three year tool protection plan.
Dremel has also introduced a Multi-Max multifunction tool to give these others a run for their money. With a 1.5 Amp motor powerful enough to cut through even a 1-1/4in. oak door jamb, Dremel's Multi-Max is truly tough. Ranging from 10,000 - 21,000 OPM (oscillations per minute) the tool has a huge speed range for optimized control and versatility. For better access to tight or confined areas, and enhanced operator control and comfort, Dremel's Multi-Max also has a compact and ergonomic design. The Multi-Max has a separate on/off switch which maintains speed setting even after the tool is shut off, and an electronic feedback to ensure consistent speed throughout even the toughest applications. The tool also features a Quick Fit mechanism which allows for faster, easier use, and changes accessories up to twice as a fast as other tools. The Dremel Multi-Max kit includes: a sanding pad with three pieces of tough sanding paper for wood, metal, and chipboard - a flexible scraper for tough removal of caulk and adhesive - a 3in. wood and drywall half-round blade which is also ideal for plastics - a 3-1/4in. wood blade for wood, plastic, and drywall cutting - and a carrying case for convenience and portability.
