Drill Bit Art-Pol HSS straight shank for metal 7.5 mm (Art-Pol 53070)

Art-Pol HSS straight shank drill bit with a 7.5 mm cutting diameter is designed for drilling holes in a wide range of ferrous and non-ferrous metals. Made from high-speed steel (HSS), this drill bit combines wear resistance and heat tolerance suitable for general metalworking, repair and maintenance tasks. The straight (cylindrical) shank is compatible with standard hand drills and drill presses, offering stable clamping and straightforward use in workshop and site environments.

Advantages

The high-speed steel material provides good hardness and thermal stability during medium-speed drilling operations, reducing premature wear and preserving cutting geometry. The straight shank ensures compatibility with common chucks and collets, while the 7.5 mm cutting diameter gives a balance between hole size and drilling control for many metalworking applications. The bit's geometry and material make it suitable for repeated use in maintenance, assembly and light production tasks.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminum and non-ferrous alloys
• Use with handheld electric drills and bench or pillar drill presses
• Maintenance, repair and light fabrication work
• Creating clearance holes for bolts, rivets and fasteners

Key specifications

• Material: high-speed steel (HSS)
• Shank type: straight (cylindrical)
• Cutting diameter: 7.5 mm
• Suitable machines: handheld drills and drill presses
• Typical applications: metal drilling, maintenance and assembly

How to use

Secure the drill bit in the chuck or collet so the shank is held firmly and centered. Use cutting fluid or lubricant when drilling tougher steels to reduce heat and extend tool life. Start at a low speed to establish the hole, then increase speed within the recommended range for HSS bits and the specific metal being drilled. Apply steady, moderate pressure and allow the bit to cut without excessive force; periodically withdraw the bit to clear chips and reapply coolant as needed.

Usage recommendations

For best results, use appropriate cutting speeds and a compatible lubricant for the metal type. When drilling stainless steels or hardened materials, reduce feed rate and use more coolant to prevent work hardening and overheating. Inspect the bit for wear and re-sharpen or replace when cutting performance declines.
