Product Description

Application :
Ideal for machining pre-drilled holes for capped screw or bolt helical edges.

Advantage :
*The entire blade is heat treated and ground, with a smooth blade surface, low chip removal resistance, and high hardness and precision, ensuring smooth and efficient cutting.
*Spiral groove ensures smooth and light chip removal
*Longer working life than straight groove type
*Select high-quality high-speed steel 6542 for grinding. Its high rigidity and wear resistance effectively guarantee the tool life.
*New technology, one-time molding as a whole, stable dimensions, precision quenching.
*The head and handle are concentric, that is, the flat head guide post and the concentric hole on the handle are positioned concentrically, with no difference in accuracy.
*Universal chamfered round shank, with good compatibility and adaptability, enhances the shock resistance and cutting speed of the countersunk head tool, and the clamping is tighter and does not slip.
*Easy to install, no special chuck required, almost all rotary processing equipment and tools can be used
*Thickened four-section blade, 14o rake angle design, specially designed for shock resistance and processing durability.
*Wide range of applications, not only suitable for chamfering of ordinary machined parts but also suitable for chamfering and deburring of precision difficult-to-chamfer parts. 
*High working efficiency. Due to its elastic strength, it can achieve fast processing operations and obtain good processing results.
*Can be repaired repeatedly, suitable for mass production, effectively reducing costs.

Applicable scope and prohibited materials :
√: No. 45 steel, aluminum alloy, iron, copper, wood, plastic, mold steel (HRC<32^o), carbon steel (HRC<32^o), structural steel (HRC<32^o)
×: Martensitic stainless steel, ferritic stainless steel, precipitation hardened stainless steel, mold steel with HRC≥32^o
Recommended matching models :
CNC machine tools, turret milling machines, gantry milling machines, end milling machines, CNC machining centers

Precautions :
*Ordinary milling machines can also be used with ease.
* During operation, cutting fluid needs to be added to protect the knife edge and make cutting smoother.
