## Summary description

Proline drill bit model 77140, single 14 mm diameter bit with 160 mm overall length designed for drilling metal. Solid construction suitable for hand drills and drill presses. Intended for cutting through steel and other ferrous materials; useful for fabrication, maintenance, and repair tasks where a 14 mm hole is required.

## Long description

Proline drill bit 14 mm x 160 mm, model 77140, is a high-speed steel (HSS) bit engineered for drilling metal. The single-piece bit has a 14 mm cutting diameter and 160 mm overall length, designed to be used in hand drills and drill presses for fabrication, maintenance and repair tasks requiring precise 14 mm holes in steel and other ferrous materials. The bit is fully ground to ensure straightness and high dimensional accuracy, and features a 135° point angle with chamfering adjustment to reduce the need for extensive center punching and to speed up drilling.
Advantages
The drill bit is made entirely by grinding from refined high-speed steel, delivering improved abrasion resistance, higher toughness and enhanced torsional strength compared with conventional cylindrical drills. The 135° point geometry and chamfering adjustment promote quick drilling starts and better guidance, while the fully ground construction ensures greater precision and straight holes. The bit’s design supports reliable performance in repetitive metalworking operations.
Suitable for
Drilling 14 mm holes in steel and other ferrous metals
Metal fabrication and assembly work
Maintenance and repair tasks on machinery and structures
Use with hand-held drills and drill presses
Key specifications
Cutting diameter: 14 mm
Overall length: 160 mm
Material: refined high-speed steel (HSS)
Point angle: 135° with chamfering adjustment
Manufacturing: fully ground flute and body for precision and straightness
Enhanced abrasion resistance, resilience and torsional strength
How to use
Secure the workpiece and mark the drilling position; use a center punch if required to help initial positioning. Install the 14 mm drill bit in the chuck of a hand drill or drill press, tightening the chuck to prevent slippage. Select an appropriate cutting speed for HSS when drilling steel (moderate speeds for harder materials), apply steady feed pressure without forcing, and use cutting lubricant or coolant to reduce heat and extend bit life. Clear chips regularly and allow the bit to cool between long passes to maintain cutting performance.
Usage recommendations
For best results when drilling metal, use cutting fluid, maintain correct rotational speed for the material, and clamp both workpiece and tool securely. Replace the bit if wear or deformation occurs to preserve hole quality and operator safety.
