## Summary description

Proline 77175 metal drill bit, single piece with 17.5 mm cutting diameter and 191 mm overall length. Designed for drilling metal and similar materials, this straight-shank bit suits handheld drills and drill presses. Use for creating medium-diameter holes in fabrication, repair and installation tasks where precise 17.5 mm holes are required.

## Long description

Proline 77175 metal drill bit with a 17.5 mm cutting diameter and 191 mm overall length is engineered for precise medium-diameter holes in metalworking, repair and installation tasks. The bit features a straight shank compatible with handheld drills and drill presses. Manufactured from high-quality refined HSS and produced entirely by grinding, this drill delivers high concentricity and straightness of holes for consistent results when a reliable 17.5 mm opening is required.
Advantages
The Proline 77175 uses a 135° point angle with chamfering adjustment to enable fast penetration and reduced need for centre punching. Being fully ground rather than cylindrical or precision ground increases drilling efficiency and accuracy. Made from refined HSS, the bit offers increased abrasion resistance, improved resilience and enhanced torsional strength for longer service life under typical metal drilling conditions. The product is supplied in a protective plastic rectangular tube suitable for safe storage and transport.
Suitable for
 Drilling holes in steel sheets, plates and structural metal components
 Fabrication and workshop tasks requiring a precise 17.5 mm hole
 Repair and installation work with handheld drills or bench drill presses
 Creating holes for fasteners, bushings or pipe fittings in metal
Key specifications
 Cutting diameter: 17.5 mm
 Overall length: 191 mm
 Point angle: 135° with chamfering adjustment
 Shank type: straight shank for handheld drills and drill presses
 Material: high-speed steel (refined HSS), fully ground
 Characteristics: increased abrasion resistance, improved resilience and torsional strength
 Packing: single piece in a protective plastic rectangular tube
How to use
Secure the workpiece and mark the drilling position accurately. Select an appropriate drill speed for the metal being drilled and clamp the Proline 77175 bit firmly in the chuck of a handheld drill or drill press. If necessary, use a centre punch to define the start point; the 135° point angle with chamfering adjustment reduces the need for heavy centre punching. Apply steady feed pressure, allow the bit to cut without excessive force, and withdraw periodically to clear chips. Use cutting fluid for steel and harder alloys to reduce heat and extend tool life.
Usage recommendations
For best results when drilling metals, use appropriate cutting fluid, moderate spindle speeds and steady feed. Inspect the bit for wear before use and replace if cutting performance or hole quality degrades. Store the bit in its protective plastic tube to prevent damage and maintain straightness.
