The High Speed Steel twist drill bit is a rotary cutting tool made from high-speed steel, featuring spiral flutes. It is designed for drilling holes in a wide range of materials, offering excellent durability, heat resistance, and versatility.
The uncommon appearance of roasted jute twist drills are fake, and the quality is good. The overall heat treatment hardness can reach 64-68HRC,and the service life is that of ordinary twist drills.2-3 times,it has the characteristics if positioning,precise cutting and fast chip removal.The surface is treated with yellowing,and it is more wear-resistant. Sharp and durable quality assurance,trustworthy!

Drill points between normal 118°and 135° split point:
118°point angles are used primarily in softer material such as mild steels and cast irons.
2. 135°split point should be used to cut harder steel materials and especially in deep holes over 4 times the drill diameter. With a 135°split point, cutting harder materials will produce thicker chips, minimizing work hardening of the cavity short.
The length of the lips on a 135°split point, measured from the axis to the cuter corners, is relativity short. This enables
quicker penetration into the workpiece and reduces thrust and abrasion along the cutting edges.
3. When repointing a standard 118°point to 135°,make a lip correction to reduce the hook of the cutting face.

The High Speed Steel twist drill bit are made of HSS with good milling, ensure high work efficiency.
High hardness, high wear resistance and high toughness.
The drill bits in different sizes to meet varied needs.
Can be used CNC, radial drill, bench drill or hand drill chuck for drilling operations.
Precise dimension,long life and high efficiency.
High-speed steel (HSS) provides hardness for wear resistance
Bright finish increases chip flow in softer materials such as aluminum, wood and plastic
Self-centering 118-degree notched point penetrates material without a pilot hole more easily than a conventional point, and maintains a sharp cutting edge
Morse taper shank allows the tool to be inserted directly into the machine's spindle to facilitate high-torque applications such as large cut diameters
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
Designed to perform in a broad range of materials in the iron and steel families
Spiral flutes are constructed with a higher flute angle to remove chips more easily.
