Main Highlights

PACKING LIST: 2 packs of drill bits in 10mm cutting diameter, 85mm/3.35inch flute length, 130mm/5.12inch overall length, 135° split point tip.
FEATURE: The drills are made of M35 high speed steel with 4.50% to 5.50% cobalt content, which has excellent hardness, wear resistance, heat resistance and high crack resistance, making it suitable for machining hard metals. The gold finish effectively improves corrosion resistance and extends the drill bits' life.
APPLICATION: The M35 twist drill is suitable for professional machining, particularly for drilling stainless steel. It is also suitable for processing high-hardness materials, including carbon steel, iron, aluminum, copper, plastic, wood, and more.
NOTE: Position the twist drill bit at 90° to the surface of the workpiece. For thick materials, drill in multiple passes to prevent overheating or breakage. For large holes, start with a guide hole. Use cutting fluid to improve efficiency, extend tool life, and reduce material damage.
INSTRUCTION: When machining different materials, the spindle speed and feed rate vary. Generally, the harder the material, the lower the spindle speed and feed rate should be. For specific speed and feed rate recommend for common materials, please refer to the details provided on the product page.

PACKING LIST: 1 pack of drill bits in 10.0mm cutting diameter, 40mm/1.57 inch flute length, 75mm/2.95 inch overall length, 130° Point Angle
FEATURE: Cemented carbide twist drills are widely used in industrial drilling for their strong performance. They offer high hardness, high wear resistance and thermal stability, enabling effective machining of difficult-to-cut materials such as hardened steel and stainless steel, they are designed for
APPLICATION: Carbide twist drills with titanium aluminum silicon nitride coating are suitable for machining high-hardness materials due to their ultra-high hardness and heat resistance, including hardened steel, alloy steel, stainless steel, titanium alloys, cast iron, hard plastics, and wood.
130° POINT ANGLE: A characteristic feature of carbide drills, which provides enhanced cutting stability and self-centering capability through increased contact area between the drill point and the workpiece.
NOTE: Although it can machine very hard materials, cemented carbide is prone to fail in unstable working conditions or situations prone to vibration. In practical applications, it is essential to use a rigid machine tool and ensure high-precision drill chuck clamping to minimize vibration. Appropriate cutting parameters (particularly feed rate) must also be selected to avoid any form of impact load.
