## Summary description

Set of Proline Pro-Line HSS cylindrical drill bits designed for drilling metal. The set includes HSS (high-speed steel) cylindrical shank bits with 338 mm length, suitable for cutting and enlarging holes in various metal workpieces. Intended for use with compatible drilling machines and stands in metalworking, maintenance and repair tasks.

## Long description

Set of Proline Pro-Line HSS cylindrical drill bits with a total length of 338 mm, designed for drilling and enlarging holes in metal. These bits feature high-speed steel cutting edges and cylindrical shanks for stable mounting in chucks and drill stands. The set is intended for use with compatible drilling machines in metalworking, maintenance and repair applications where deeper or through-holes are required.
Advantages
HSS construction provides good hardness and heat resistance for cutting various ferrous and non-ferrous metals. Cylindrical shanks ensure straightforward clamping in standard drill chucks and machine holders. The 338 mm length enables drilling deeper holes or working with thicker metal plates without changing to extension accessories. The bits are suitable for conventional drilling speeds and feed rates typical for metalworking.
Suitable for
 Drilling and enlarging holes in steel, cast iron and non-ferrous metals
 Workshop drilling with bench or pillar drills
 Maintenance and repair tasks requiring deeper hole penetration
 Fabrication and mechanical assembly operations
Key specifications
 Material: High-speed steel (HSS)
 Shank type: Cylindrical shank for standard chucks
 Overall length: 338 mm
 Application: Metal drilling
 Compatibility: Use with compatible drilling machines and stands
How to use
Select a drill size appropriate for the hole diameter required and secure the bit in a clean, correctly sized chuck. Set the drilling machine to the recommended speed for the workpiece material and apply steady feed pressure. Use cutting fluid or coolant when drilling tougher steels or when prolonged cutting is expected to reduce heat build-up and extend bit life. Clear chips periodically to avoid clogging and inspect the bit for wear or damage before each use.
Usage recommendations
For best results, match drill speed and feed to the metal being worked: lower speeds for hard steels and higher speeds for softer non-ferrous metals. Use appropriate cutting fluid, maintain stable clamping of the workpiece, and avoid excessive side loading to preserve drill geometry and extend service life.
