## Summary description

Single Proline drill bit model 72892 designed for metalworking. Solid drill with 28 mm diameter and 920 mm overall length, supplied as one piece.

Use with compatible drill rigs or magnetic drills and appropriate speeds and coolant.

## Long description

Proline 72892 is a single solid drill bit designed for metalworking and industrial applications. With a nominal diameter of 28 mm and an overall length of 920 mm, this one-piece cutter is intended for deep-hole drilling in metal, steel and other hard materials where extended reach and a large-diameter tool are required. The carbide or reinforced tip geometry (four-blade insert with optimised geometry) and double-twist flute design support effective chip evacuation when used with appropriate coolant and compatible drill rigs or magnetic drills.
Advantages
The long 920 mm length allows access to deep or hard-to-reach workpieces without switching to extensions or multiple shorter bits. The 28 mm diameter provides a stable hole size for fitment and assembly tasks. The double twist flute promotes faster chip removal during drilling, reducing clogging and improving cutting consistency. The four-blade insert with optimised geometry increases stability at the cutting edge and helps maintain hole quality in demanding metalworking conditions.
Suitable for (tasks / use cases)
Deep-hole drilling in steel structures and thick metal plates
Fabrication and maintenance where long-reach metal drilling is required
Use with magnetic drills, drill rigs or other stationary drilling equipment
Applications requiring a 28 mm finished hole in hard materials
Key specifications

How to use
Fit the Proline 72892 drill bit into a compatible chuck or arbor following the drill rig or magnetic drill manufacturer’s instructions. Secure the workpiece and set appropriate spindle speed, feed rate and coolant flow for the material being drilled. Start drilling at a controlled feed to establish the hole, maintain steady pressure and ensure continuous coolant or lubricant supply to reduce heat and assist chip removal. Retract occasionally if chips accumulate, and inspect the cutting edge periodically for wear.
Usage recommendations
Use suitable personal protective equipment, select drill speeds and coolant compatible with the metal type, and employ stable fixturing. For best results in deep drilling, use a drill rig or magnetic drill with sufficient rigidity and power. Replace the bit when wear affects hole accuracy or cutting performance.
