Keo 907-000-064 Combo Drill Countersink 3/16 in Cobalt

Product Description

The KEO 907-000-064 is a combination drill and countersink tool machined from cobalt high-speed steel. It performs two operations in a single pass: drilling a pilot hole and cutting a countersunk seat. The body diameter is 3/16 inches, the drill point diameter is 5/64 inches, and the overall length is 3 inches. The 60-degree included angle and 118-degree drill point angle make it well suited for creating clean, accurate countersink seats in steel, stainless, cast iron, and other hard or abrasive materials where cobalt tooling is the standard choice. The bright, uncoated finish allows easy visual inspection of the cutting edges between uses.

This tool is used in metal fabrication shops, maintenance and repair operations, and production machining environments where a reliable center drill and countersink combination is needed. The right-hand cutting direction and plain cutting edge style fit standard drill press, CNC, or hand-held drill applications. Its long-length designation provides additional reach for deep setups or when working in recessed areas. Trade size 2 designates the standard sizing used by machinists and toolroom technicians when selecting center drill sets.

Key Features

• Cobalt high-speed steel construction for improved heat and wear resistance in hard materials
• 118-degree drill point angle with 60-degree included angle for accurate countersink geometry
• Combination drill and countersink design completes two operations in one pass
• 3-inch overall length qualifies as a long-length tool for extended reach applications
• Bright, uncoated finish with right-hand cut and plain cutting edge style
• Double end type doubles usable tool life before replacement is needed

Compatibility

Designed as an OEM-style replacement or direct substitute for trade size 2 combination drill and countersink tooling used in standard drill press, CNC lathe, and hand-drill applications requiring a 3/16-inch body diameter.

Installation Notes

Installation of this tool is performed by machinists or qualified tool operators. Secure the shank firmly in a collet or drill chuck rated for the body diameter before operation. Ensure the spindle is at a full stop before inserting or removing the tool. Follow shop safety protocols and applicable OSHA machine guarding requirements when operating drill press or CNC equipment.
