Keo 919-000-299 Countersink 3/16 in 60 Degree 6 Flutes Hss

Product Description

The KEO 919-000-299 is a single-end countersink designed for producing chamfered holes in metal and other machinable materials. It features a 3/16 inch head diameter with a 60-degree included angle, making it suited for standard fastener seating and deburring operations. Six flutes provide smooth cutting action and efficient chip evacuation. Constructed from high-speed steel, this countersink handles the heat and wear demands of production and maintenance machining environments. The straight-cylindrical shank measures 3/16 inch in diameter for secure chuck holding. Right-hand cutting direction is standard for conventional drill press and CNC spindle use.

This countersink fits into general metalworking, sheet metal fabrication, and light production machining workflows where a small-diameter 60-degree countersink is required. It is appropriate for countersinking pilot-free applications in ferrous and non-ferrous metals. The compact 3/16 inch head diameter makes it well suited for tight clearance work and smaller fastener sizes. Machinists, tool-and-die technicians, and maintenance mechanics will find it suitable for bench drill, drill press, and CNC lathe or mill use.

Key Features

• 3/16 inch head diameter with 60-degree included angle for standard fastener seating
• Six flutes for smooth cutting action and improved chip clearance
• High-speed steel construction for heat resistance and edge retention
• Straight-cylindrical shank for easy chuck mounting
• Right-hand cut direction compatible with conventional spindle rotation
• No pilot required - single-end design for direct countersinking

Compatibility

Designed as a standard single-end countersink for use in drill presses, CNC mills, and lathes equipped with a chuck or collet accepting a 3/16 inch straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or technician familiar with rotary cutting tools. Secure the straight-cylindrical shank firmly in a suitable chuck or collet before operation and verify runout is within acceptable limits. Always power down the machine and bring the spindle to a full stop before changing or adjusting the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve a clean finish.
