Carbide Burrs and Rotary Files


GENERAL RECOMMENDATIONS

For maximum control, and to prevent whipping and chatter, insert the shank of the carbide burr into the chuck as far as possible. Avoid excessive pressure, which slows the spindle speed of your die grinder, and also damages the burr's cutting edges. Avoid using burrs and rotary files beyond normal resharpening. Otherwise, the resultant heat and pressure will cause excessive chipping, and possibly tool braze failure.


What makes a great carbide burr? Quality of construction is an important factor. The most durable and reliable carbide round tools are manufactured from premium-quality micrograin carbide, carbide burrs and rotary files included. Micrograin carbide made in the U.S.A. is especially reputable because, unlike carbides manufactured in other parts of the world, it is subjected to strict quality controls and manufacturing standards.

Design is another important consideration in quality cutting tools. Carbide burrs should be designed not only to handle material precisely and effectively, but they must also be conducive to the comfort and safety of the user. Any professional knows first-hand the pleasure of using well-designed tools, as well as the annoyance and discomfort caused by poor tool design.

Proper grinding of carbide burrs is essential to the tool life and overall quality. QTE's carbide burrs are ground with diamond wheels designed specifically for burr grinding, on state-of-the-art CNC grinders, assuring the user of a truly round tool with very little run out. The heads of the burrs are ground concentric to the shank, and then the teeth are carefully ground. The ground areas are clean and shiny, with no evidence of bluing or burning of the cutting edges. If your cutting edges are rainbow colored, watch out!

Economy burrs are frequently ground with too coarse a wheel, grinding too much material too quickly, and burning the cobalt binder out of the carbide. Cheap burrs are dangerous to use, as the teeth tend to fly off when the burr is applied to the material. QTE does not recommend using bargain burrs in any manufacturing environment.

Occasionally even high quality carbide burrs may shatter. That is the nature of heat-treated and hardened cutting tools. Remember, when an irresistable force meets an immovable object, something's got to give. QTE strongly recommends the use of appropriate safety glasses or goggles whenever a burr or rotary file is used.

Offerings in Carbide Burrs

It doesn't matter if you're a deburring professional working in aerospace, automotive, ship building, welding, die casting, forging, jewelry manufacturing, mold making, engine rebuilding, cylinder head porting, or simply a hobbyist.

In the cutting tool trade for over 35 years, QTE enjoys a well-earned reputation for the excellence of its products.

QTE's website www.qtena.com has a carbide burr for every application. Available in many different shapes and sizes, such as cylindrical plain end, cylindrical radius end, cone pointed, cone radius, oval, tree radius, tree pointed, ball, inverted cone, flame, deburring 60 degree, deburring 90 degree, tapered 14 degree, and the hard to find 6" extended shank extra long carbide burrs. These fine quality burrs come in standard, single cut, double cut, aluminum cut, and the new Bear cut. Bear Burrs cut faster and last longer than any burr on the market today, and are designed to save you time and money.

Carbide Burr and Rotary File Selection Guide

STANDARD CUT: also known as single cut, these carbide burrs have cuts made on the right-hand spiral. Standard cut is most commonly used for general purpose deburring and grinding of steel, cast iron and other ferrous materials, as well as some copper or brass.

DOUBLE CUT: a standard cut grinding bur, with cuts also made on the left-hand spiral. The design of these carbide burrs produces a finer finish on material and reduces the size of the chips and slivers. It also gives greater tool control with less bounce.

CHIPBREAKER CUT: single cut carbide burs, with the addition of a horizontal chip breaker that will reduce sliver size and improve operator control at a slightly reduced surface finish. Available on request. Call QTE for details.

ALUMINUM CUT: for use on aluminum, magnesium, non-ferrous and non-metallic materials such as hard plastic, rubber and wood. These Carbide Burs have wide teeth, allowing rapid stock removal with minimum chip loading.

BEAR BURR CUT: Our most aggressive Carbide Burr, engineered for heavy-duty welding and metal fabrication applications. These unique Carbide Burs are guaranteed to substantially cut production costs. The Bear Burr's design will cut and remove more material per hour. The depth and width of the teeth make them more resistant to chipping. Chips break up easier and the teeth are less prone to clogging or loading up. Not to be used on aluminum.

The most popular cut styles are QTE's Double Cut and Bear Cut Carbide Burs. Quantity buyers are urged to contact QTE for a quote. We can save you money.
