7mm Drill Bit Extra Long Shank 135° M2 HSS Nitriding Black - 2 Pack
√FEATURE:
The drill bit is made of M2 high-speed steel material, it has high hardness and wear resistance, suitable for processing medium-high hardness materials
Nitriding Black finish can enhance the surface properties of the drill bit, improving its wear resistance and corrosion resistance, thereby extending the drill bit's service life and operational efficiency.
The 135-degree split point tip angle drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, thereby improving drilling efficiency and hole quality.
The extra long drill features a high precision shank that fits tightly with the drill chuck. It ensures stable clamping without wobbling, guarantees drilling stability throughout the process, and easily meets deep-hole drilling requirements.
√APPLICATION:
The bits are suitable for various hard metals, such as steel, alloy cast iron, carbon steel, stainless steel, iron, copper, aluminium alloy, and cast iron. They are also effective in plastics and wood.
√PACKING LIST:
-Cutting Edge Diameter: 7mm/0.28inch
-Shank Diameter: 7mm
-Flute Length:
-Total Length: 250mm/9.84 inch
-Package Content: 2pcs x Drill Bit
√NOTE:
When machining different materials, the spindle speed and feed rate vary.
Generally, the harder the material, the lower the spindle speed and feed rate need to be.
Position the twist drill at 90° to 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.
For specific speed and feed rates recommended for common materials, please refer to the details provided on the product page.
