Drill bit Proline 76200P, metal, Ø20 mm, length 205 mm, 1 pc

Proline 76200P is a single HSS drill bit intended for drilling metal with a 20 mm cutting diameter and a total length of 205 mm. Manufactured from refined high-speed steel and produced to the DIN 338 geometry, this bit suits both hand-held drills and drill presses for medium-depth metal holes. The 13 mm relief and the included PVC case make handling and storage straightforward for workshops, maintenance tasks, and fabrication environments where a reliable 20 mm hole is required.

Advantages

The HSS refined steel construction provides good hardness and heat resistance during continuous drilling in ferrous and non-ferrous metals. Conformance to DIN 338 geometry ensures consistent point angle and flute design for predictable chip evacuation and stable drilling. The 13 mm relief reduces friction along the shank area, improving centring and reducing the risk of jamming. Supplied in a PVC case, the bit is protected during transport and storage, helping retain cutting performance between uses.

Suitable for

• Creating 20 mm clearance holes in sheet and plate metal
• Mounting brackets and fixtures on metal structures
• General metal fabrication and maintenance drilling
• Use with hand-held electric drills and drill presses for medium-depth holes

Key specifications

• Cutting diameter: 20 mm
• Total length: 205 mm
• Material: high-speed steel (HSS), refined
• Standard geometry: DIN 338
• Relief length: 13 mm
• Package: single piece in a PVC case

How to use

Secure the workpiece and mark the drilling point before starting. Fit the 20 mm Proline HSS bit into the drill chuck and tighten firmly. Select an appropriate speed for metal drilling — generally moderate speed for this diameter — and use cutting fluid to reduce heat and improve chip evacuation. Apply steady pressure without forcing the bit; withdraw occasionally to clear chips if drilling deep holes. After use, wipe the bit clean and return it to its PVC case for storage.

Usage recommendations

Use cutting fluid when drilling thicker or harder metals to extend tool life. For best results with the DIN 338 geometry, keep drill speed moderate and avoid excessive side loads. Inspect the cutting edges before use and replace the bit if excessive wear or chipping is present.
