Drill bit Proline HSS cylindrical 17 mm for metal, model 76170

Proline HSS cylindrical drill bit 17 mm for metal is a solid high-speed steel cutting tool designed for precise drilling in ferrous and non-ferrous metals. The 17 mm diameter and cylindrical shank make it compatible with standard chucks and bench drills, while the HSS material provides the hardness and heat resistance required for repeated metal cutting operations. This tool is intended for making through-holes with clean edges and consistent diameter in workshop, maintenance, and industrial metalworking environments.

Advantages

The HSS construction ensures good wear resistance and edge retention during drilling in steel, cast iron, aluminium and other common metals. The cylindrical shank offers reliable clamping in standard drill chucks for stable rotation and reduced runout. The 17 mm diameter delivers a balance between hole size and structural integrity, suitable for many fastening and assembly tasks. The bit is manufactured to deliver straight, accurate holes and a clean finish when used with appropriate speeds and cooling.

Suitable for

• Drilling through-holes in steel and cast iron
• Creating clearance holes in aluminium and non-ferrous metals
• Workshop and maintenance drilling on bench or handheld drills
• Industrial metalworking tasks requiring consistent 17 mm holes

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 17 mm
• Shank type: cylindrical (straight)
• Intended use: metal drilling (ferrous and non-ferrous)
• Typical applications: through-holes, clearance holes, assembly work

How to use

Secure the drill bit in a properly tightened standard chuck or collet ensuring minimal runout. Select an appropriate spindle speed and feed rate for the metal being drilled—lower speeds for harder steels, higher speeds for aluminium—referencing standard drilling speed charts. Use cutting fluid or coolant to reduce heat, extend tool life and improve finish when drilling into harder materials. Clamp the workpiece firmly to prevent movement and drill with steady, even pressure until the required depth is reached.

Usage recommendations

For best results, pre-center the hole with a punch or pilot drill, use appropriate coolant for steel, and withdraw periodically to clear chips. Inspect the bit regularly for wear or chipping and replace when cutting performance declines.
