Keo 906-000-333 Combo Drill Countersink Metric Hss

Product Description

The KEO 906-000-333 is a combination drill and countersink designed for metric drilling and countersinking operations in a single tool pass. Manufactured from high-speed steel with a bright uncoated finish, it cuts right-hand with a plain cutting edge and delivers a 60-degree included angle countersink profile. The drill point angle is 120 degrees, and the tool features a double end type, extending useful tool life before replacement. It is sized for light-duty precision work and used in metal fabrication, maintenance, and machine shop environments by machinists and tooling technicians.

This combo drill countersink is suited for metric countersinking applications in ferrous and non-ferrous metals. The plain cutting edge style and right-hand cut make it compatible with standard drill press, lathe, or CNC spindle setups. Its double-end configuration allows the operator to flip the tool when one end dulls, maximizing value per unit. This tool is not aircraft-style and is not a long-length variant, making it appropriate for standard-depth countersinking tasks in general metalworking.

Key Features

• High-speed steel construction for durability across ferrous and non-ferrous materials
• 120-degree drill point angle for accurate center-drilling and countersinking
• 60-degree included angle for standard metric countersink profiles
• Double-end design extends service life before replacement
• Bright uncoated finish suitable for general-purpose applications
• Right-hand cut, plain cutting edge for compatibility with standard spindle setups

Compatibility

Designed as a general-purpose metric combo drill countersink for use in drill press, lathe, or CNC spindle setups requiring a 60-degree included angle countersink profile.

Installation Notes

Installation is performed by machinists or tooling technicians using a standard drill chuck or collet rated for the tool body diameter. Secure the tool firmly and verify spindle direction is set to right-hand rotation before operation. Use appropriate cutting fluid for the workpiece material to preserve cutting edge life. Inspect both ends of the double-end tool regularly and replace when wear affects hole quality.
