BB High Performance Drill
M42 high speed steel
W2Mo9Cr4VCo8, the steel has high hardness up to 70HRC, good thermal hardness, high high temperature hardness and easy grinding.
Application
For carbon steel, cast iron, alloy steel, tool steel,
copper, aluminum, brass,
oak, maple, MDF, PVC, polycarbonate, acrylic, ABS, nylon and composite materials.
Edge Cleaning Design
Adopting a circular arc blade with edge cleaning design, the milling cutter has less wear during milling, and the blade is durable and sharp, matched with a 35 ° spiral flute for smooth chip removal.
Effect Comparison

High precision precision Fried Dough Twists Drill
The drill bit has good straightness, small bounce, and is not prone to deviation during drilling, achieving continuous and stable aperture processing
DRILLING TIPS
1，Please use good equipment, the better the performance, the higher the machining hardness.
2、Appropriate cutting parameters can help extend the service life of the drill bit.
3、During manual operation, the processing skills and experience will help the processing efficiency and life.
4、Please cooperate with the applicable Cutting fluid to ensure that the cooling is in place and the cutting is smooth.
5、Brute force operation and violent cutting are strictly prohibited. This situation undoubtedly causes rapid damage to the drill bit, and in severe cases, it can lead to the drill bit breaking or overheating and burning.
Conditions
-The workpiece must be firmly supported, without a chance to bounce or bend
-Additional support points will help
-With thin-walled workpieces, reed must be reduced
-It is better to have a cooling system to ensure the cooling temperature.
-With large clamping-related extension lengths, it is necessary to provide either a centering or a pilot hole.
Material
①M2 High-Speed steel with black oxide.
②M35 High-Speed steel with cobalt.
③M42 HSS-Co8
④Solid Carbide.
Solid Carbide
More expensive but longer life, running fast ,lower cost per hole, good heat and chip resistance.
Coating:TiALN,TiSiN,AlTiSiN
Higher performing ,higher temperature,Good for steels and stainless steels.
Tungsten steel alloy makes the drill hardness higher, and a stable processing environment should be provided.
