Keo 76012 Hss Combo Drill Countersink Set 5 Pc

Product Description

The KEO 76012 is a 5-piece high speed steel combination drill and countersink set covering trade sizes 1 through 5. Each tool combines a center-drilling tip with a 60-degree included angle countersink profile in a single body, allowing the technician to drill and countersink a workpiece in one operation. The plain edge cutting geometry is suited for general-purpose metalworking and fabrication. High speed steel construction provides durability across a range of common ferrous and non-ferrous materials. The set is a practical solution for shops and field crews who need consistent countersink geometry without swapping between separate tools.

This set is intended for use in metal fabrication, mechanical assembly, and maintenance applications where countersunk fastener seats are required. The five-size range covering sizes 1 through 5 makes it appropriate for work across varied fastener dimensions in a single kit. Machinists, millwrights, and maintenance technicians working in industrial, commercial, or light manufacturing environments will find the full size range useful for everyday countersinking tasks on drill presses, mills, or hand-held power tools.

Key Features

• 5-piece set covering trade sizes 1 through 5 in a single kit
• 60-degree included angle matches standard countersunk fastener geometry
• Plain edge cutting profile for general-purpose metal drilling and countersinking

Compatibility

Designed as a general-purpose combination drill and countersink set compatible with standard drill presses, milling machines, and hand-held rotary power tools accepting straight-shank tooling in the applicable shank sizes.

Installation Notes

Combination drill and countersink tools should be installed in a properly sized chuck and secured before operation. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain cutting edge integrity. Operator PPE including eye protection is required during all drilling and countersinking operations.
