Product Description

 

Main parameters:
Diameter: Twist drill bits have a wide range of diameters, usually between 0.25 mm and 80 mm, and can even reach 100 mm to meet the machining needs of different hole diameters.
Helix angle: The helix angle of the twist drill mainly affects the size of the rake angle on the cutting edge, the strength of the blade flap and the chip removal performance. The helix angle of the standard twist drill bit is usually 25°~32°.
Top angle: The top angle of the cutting part of the standard twist drill bit is 118°.
Cross edge bevel: The cross edge bevel angle of twist drill bits is usually between 40°~60°.
Rear angle: The range of the rear angle of the twist drill bit is 8°~20°, which is used to reduce friction and wear during cutting

Performance characteristics:
Good rigidity: Twist drill bits are usually made of high-quality steel, which has high rigidity and strength, and is not easy to bend and break.
Smooth chip removal: The spiral groove design of the twist drill bit makes the chip removal smooth, which effectively avoids the phenomenon of chip clogging and winding of the drill bit.
Light cutting: By grinding the cross edge and tooth back, the twist drill can reduce the axial force and achieve light cutting.
High machining accuracy: The twist drill bit has been precision manufactured and sharpened, which has high machining accuracy and stability, which can ensure the accuracy and dimensional consistency of machining holes.
