Metal drill bits HSS-G Standard, Bosch, set 1pc (MPN 2608585918)

Single Bosch HSS‑G Standard metal drill bit designed for drilling steel and other ferrous materials. Made from high‑speed steel (HSS‑G), this drill bit offers increased hardness and resistance to heat during continuous drilling operations. The product is intended for general metal fabrication, maintenance and repair tasks and can be used with hand drills and drill presses in workshop or professional environments.

Advantages

The HSS‑G material provides a balance of toughness and wear resistance suitable for cutting into ferrous metals. Its standard geometry ensures reliable centring and steady chip removal when used at recommended speeds and with appropriate lubrication. The single‑piece design minimises vibration and runout when mounted in a drill chuck, delivering consistent hole quality for repeated use.

Suitable for

• Drilling mild and medium carbon steels
• Maintenance and repair of metal components
• Workshop bench work with hand drills and drill presses
• Creating pilot and clearance holes in metal fabrications

Key specifications

• Material: high‑speed steel (HSS‑G)
• Intended workpiece: ferrous metals (steel and similar alloys)
• Design: standard twist drill geometry for metalworking
• Compatibility: designed for use in handheld drills and drill presses
• Finish: ground flutes for chip evacuation and stable cutting

How to use

Secure the drill bit properly in the chuck, ensuring minimal runout. Select drill speed appropriate for the diameter and type of steel being drilled; lower speeds for larger diameters or hard steels reduce heat build‑up. Use cutting fluid or oil to improve lubrication and chip evacuation, prolonging tool life and improving hole quality. Apply steady, moderate feed pressure and back out periodically if long chips form to clear the flutes.

Usage recommendations

For best results, pre‑centre with a punch for precise positioning, use appropriate cutting lubricant for ferrous metals, and avoid excessive speed or feed that can cause premature wear. Inspect the bit before use and replace when signs of significant wear or chipping appear to maintain hole accuracy and safety.
