## Summary description

Single Proline drill bit model 77190 designed for drilling metal. Solid bit with a diameter of 19 mm and overall length of 198 mm, supplied as one piece. Suitable for drilling through steel and other ferrous materials in construction, metalworking and repair tasks, compatible with standard drill chucks for workshop and job-site use.

## Long description

Proline 77190 is a single HSS metal drill bit with a 19 mm diameter and an overall length of 198 mm, designed for drilling steel and other ferrous materials. Manufactured by precision grinding, this solid drill bit delivers straight, accurate holes and is compatible with standard drill chucks used in workshops and on construction sites. The 135° point angle with chamfering adjustment reduces the need for extensive centre punching and enables fast penetration into metal surfaces.
Advantages
The drill bit is made from high-quality refined high-speed steel (HSS) for increased abrasion resistance and enhanced torsional strength. Fully ground construction ensures better concentricity and hole straightness compared with cylindrical or precision-ground alternatives. The 135° split point geometry improves cutting efficiency and reduces walking at the drill start, saving time during setup and drilling. Supplied as a single piece in protective packaging, the bit is suitable for heavy-duty metalworking and repair tasks.
Suitable for
 Drilling holes in steel and other ferrous metals
 Metal fabrication and workshop use
 Construction site drilling and repair work
 Use with hand-held and bench drills with standard chucks
Key specifications
 Material: refined high-speed steel (HSS)
 Diameter: 19 mm
 Overall length: 198 mm
 Point angle: 135° with chamfering adjustment (split point)
 Manufacturing: fully ground flute and body for high precision
 Properties: increased abrasion resistance and torsional strength
 Packaging: single piece in protective plastic tube
How to use
Secure the drill bit firmly in a compatible drill chuck and set the drill to an appropriate speed for HSS bits and the thickness of the metal being drilled. Mark the drilling position; the 135° split point reduces walking, but a centre punch can still be used for best accuracy on thin or hardened surfaces. Use cutting lubricant for improved tool life and lower cutting forces when drilling steel. Apply steady, even pressure and withdraw occasionally to clear chips on deep holes.
Usage recommendations
For optimal performance and longer service life, use appropriate cutting fluid, avoid excessive feed pressure, and select drill speeds suited to the workpiece material and diameter. Inspect the bit for wear or damage before use and replace when the cutting edges become rounded or chipping occurs.
