Drill bit Proline 72432 — metal bit Ø24 mm, length 320 mm, 1 pc

Proline 72432 drill bit is a single-piece metal drilling bit with a 24 mm diameter and 320 mm overall length, supplied as one unit for use with compatible drill chucks and machines. Designed for industrial and professional applications, this drill bit is intended to create larger-diameter or deeper holes in metal workpieces, supporting fabrication, repair and construction tasks that require precise metal drilling.

Advantages

The Proline 72432 combines a large 24 mm cutting diameter with an extended 320 mm length to reach deeper hole depths. Its double twist design facilitates efficient chip and dust removal during drilling operations, while the 4-blade insert with optimized geometry improves cutting stability and reduces the tendency to wander. Supplied as a single unit, it is ready for installation in suitable drill chucks and machines for professional metalworking tasks.

Suitable for

• Drilling large-diameter holes in steel and other metals
• Fabrication and metal repair work requiring deeper penetration
• Installation and construction tasks that need precise metal bores
• Workshop and on-site professional drilling with compatible chucks

Key specifications

• Cutting diameter: 24 mm
• Overall length: 320 mm
• Quantity in package: 1 piece
• Intended material: metal
• Tip and flute design: double twist with 4-blade insert and optimized geometry for chip evacuation

How to use

Secure the Proline 72432 drill bit in a compatible drill chuck or machine according to the equipment manufacturer's instructions. Mark and center the drilling point on the metal workpiece, apply appropriate cutting speed and feed for the metal type, and use steady, moderate pressure. Coolant or cutting fluid is recommended for prolonged drilling in metals to reduce heat buildup and extend tool life. After drilling, retract the bit while the machine is still running briefly to clear remaining chips, then stop the machine and remove the bit once rotation has ceased.

Usage recommendations

For best results when drilling metal, use appropriate cutting fluid and select spindle speeds and feed rates matched to the metal grade. Check the drill chuck tightening before each operation and replace the bit when wear reduces cutting performance.
