## Summary description

Single Proline 77200 metal drill bit with a 20 mm cutting diameter and 205 mm overall length. Designed for drilling metal and suitable for hand-held and bench drills; provides a single dedicated bit for through-holes and metal fabrication tasks. Compatible with standard drill chucks and intended for workshop and construction use.

## Long description

Single Proline 77200 metal drill bit with a 20 mm cutting diameter and 205 mm overall length, designed for drilling steel and other metals. The bit is made entirely by grinding from refined high-speed steel (HSS) and features a 135° point angle with chamfering adjustment for fast, accurate starts and reduced need for centre punching. It is compatible with standard hand-held and bench drills and supplied in a protective plastic tube for safe storage and handling.
Advantages
The fully ground construction ensures high precision and straightness of holes, delivering greater efficiency compared with cylindrical or standard ground drills. The HSS material provides increased abrasion resistance, improved resilience and enhanced torsional strength for longer service life under typical workshop and construction conditions. The 135° point with chamfer adjustment enables quicker penetration and better centring on metal surfaces.
Suitable for
Drilling through-holes in steel and non-ferrous metals
Metal fabrication and assembly work in workshops
Hand-held drilling and bench drill operations
Construction site metalwork and retrofit tasks
Key specifications
Cutting diameter: 20 mm
Overall length: 205 mm
Point angle: 135° with chamfering adjustment
Material: refined high-speed steel (HSS), fully ground
Characteristics: increased abrasion resistance, high torsional strength, precise straightness
Compatibility: standard drill chucks for hand-held and bench drills
Packaging: plastic protective tube for single-piece size range
How to use
Secure the drill bit in a compatible chuck and tighten firmly to avoid slippage. Mark and, if necessary, centre-punch the drilling location; the 135° point facilitates accurate starts and may reduce the need for a deep centre punch. Use appropriate cutting speed and lubrication for the metal being drilled to extend tool life and improve hole quality. Apply steady pressure without forcing the bit; withdraw periodically to clear chips when drilling deeper holes.
Usage recommendations
For best results, select cutting speeds and feed rates suited to the specific metal and thickness. Use cutting fluid or oil for steel and other hard materials to reduce heat and wear. Inspect the bit for wear or tip damage before use and store it in its protective tube between jobs to maintain point geometry and prevent accidental damage.
