Drill bit Proline 72867, metal, Ø 28 mm, length 670 mm, 1 pc

Single metal drill bit Proline 72867 with a 28 mm diameter and 670 mm overall length. Designed for drilling metal, the solid bit is intended for through-holes and deep drilling in steel and other ferrous materials. Supplied as a single piece, it is compatible with chucks that accept long-shank bits and intended for industrial or workshop use where extended reach and metal-cutting capability are required.

Advantages

The Proline 72867 drill bit is manufactured as a solid metal bit with a 28 mm cutting diameter and an overall length of 670 mm, providing extended reach for deep holes. Its geometry is optimized for metal drilling to maintain cutting performance during prolonged use. Delivered as one piece, the bit fits standard chucks that accept long shanks, enabling use in bench drills, radial drills and portable drills with appropriate capacity. The tool is suitable for repeated drilling in ferrous materials and engineered for stability and straightness during long-reach operations.

Suitable for

• Drilling through-holes and deep holes in steel and other ferrous metals
• Industrial and workshop metalworking applications
• Use in drills with chucks that accept long-shank bits
• Tasks requiring extended reach or access to recessed areas

Key specifications

• Material application: metal, primarily ferrous materials
• Cutting diameter: 28 mm
• Overall length: 670 mm
• Configuration: solid single-piece drill bit

How to use

Secure the Proline 72867 drill bit in a compatible chuck, ensuring the shank is clamped firmly and concentric. Select an appropriate rotational speed and feed for the diameter and the metal being drilled; reduce speed for hard steels and increase feed gradually while monitoring chip formation. Use cutting fluid suitable for metal drilling to reduce heat and extend tool life. Apply steady pressure and allow the bit to cut without excessive force to avoid deflection. Withdraw periodically to clear chips when drilling deep holes.

Usage recommendations

For best results, use the bit in machines capable of handling its length and diameter, apply appropriate cutting fluid, and maintain a steady, controlled feed. Inspect the bit for wear before use and replace when cutting performance deteriorates.
