Tungsten Double Cut Carbide Burrs For Rapid Stock Removal In The
Harder Materials
The difference between double slot and single slot:
The double groove has a cross pattern, which is suitable for
objects with low density. For example: used in wood, plastic,
aluminum, etc.! The cross-patterned chip evacuation is fast, and it
is not easy to block the pattern when grinding and engraving, so
double grooves on soft objects are more suitable!
The texture of the single groove determines that it is not ideal to
use a softer object, because when the single groove knife is
working and cutting, the broken waste will easily block the groove,
which causes the texture of the groove to become shallower and the
cutting ability decreases; It's what we usually say the knife is
not fast! Single slot is more suitable for hard objects such as
iron, copper and steel.
Carbide rotary file features:
Cemented carbide has a series of excellent properties such as high
hardness, wear resistance, good strength and toughness, heat
resistance, etc., especially its high hardness and wear resistance,
which remain basically unchanged even at a temperature of 500°C. It
still has high hardness at 1000°C.
Cemented carbide is widely used as tool materials, such as
turning tools, milling cutters, planers, drills, boring cutters,
etc., for cutting cast iron, non-ferrous metals, plastics, chemical
fibers, graphite, glass, stone and ordinary steel, and can also be
used for cutting Heat-resistant steel, stainless steel, high
manganese steel, tool steel and other difficult-to-process
materials.
1. High hardness (86～93HRA, equivalent to 69～81HRC);
2. Good thermal hardness (up to 900～1000℃, keeping 60HRC);
3. Good wear resistance.
The cutting speed of cemented carbide tools is 4 to 7 times higher
than that of high speed steel, and the tool life is 5 to 80 times
higher. Manufacturing molds, measuring tools, life span is 20 to
150 times longer than alloy tool steel. It can cut hard materials
of about 50HRC.

Operation note:
Carbide rotary files are mainly used on pneumatic or electric drive
tools. The speed is generally 6000-50000 rpm. When using, clamp the
tool in the right direction. The cutting method is preferably
up-milling. Do not cut reciprocatingly. Pay attention when working.
Chips fly away, prepare for work.
