Feature

●Twist Drill Bits: Drill Diameter: 4mm; Flute Length: 25mm; Overall Length: 45mm; Cutting Hardness (Max.) : HRC45 spiral tip space is designed to provide fast and clean cutting removal. Sharp edge allows for smooth cutting and no glitch
●Wide application: Widely used for drilling non-ferrous metal, cast iron, stainless steel, aluminum, copper, alloy steel, plastic and wood. Designed with base board without additional coatings and is suitable for a wide range of applications
●Material: Drill bit made of medium-grain C2/K20 tungsten carbide, has excellent toughness, hardness (HRA89), and abrasion resistance, excellent milling machine and cutting performance for improved work efficiency. The carbide tool will cut faster than other substrates
●Features: Spiral shavings space design for quick and clean shavings removal Sharp edge provides smooth cutting and no glitch. Proper lubricant helps in cutting or cooling, facilitating cutting, improving smoothness and dimensional accuracy
●Tips: Used in machining center, CNC lathe. The longer the length of the tool you clamp with the chuck, the better! If the clamp length is short, you need to lower feed and cutting speed to reduce vibration and extend tool life

Description:

The drill bit made of medium-grain C2/K20 tungsten carbide, has excellent toughness, hardness (HRA89), and abrasion resistance, excellent milling machine and cutting performance and ensures high processing efficiency. Carbide tools provide longer tool life and faster cutting speed than other substrates.

Widely used for drilling non-ferrous metals, cast iron, stainless steel, aluminum, copper, alloy steel, plastic, wood, etc. Designed with base board without additional coatings and is suitable for a wide range of applications.

Spiral shavings space design for quick, clean shavings removal Sharp edge provides smooth cutting and no glitch. Proper lubricant helps in cutting or cooling, facilitating cutting, improving smoothness and dimensional accuracy.

Used in machining centers and CNC lathes The longer the length of the tool you clamp with the chuck, the better! If the clamp length is short, you need to lower feed and cutting speed to reduce vibration and extend tool life.

Tip: In combination with the materials to be processed, select the appropriate feed and cutting speed to extend the life of the tool and improve the accuracy and performance.
