Magafor 80091504000 Combo Drill Countersink Size 4 Cobalt

Product Description

The MAGAFOR 80091504000 is a combination drill and countersink designed to drill and chamfer in a single pass. It features a 5/16-inch body diameter, a 1/8-inch drill point diameter, and an overall length of 2.125 inches. The tool is manufactured from cobalt high-speed steel and carries a TiAlN coating for improved heat resistance and extended tool life in demanding materials. The 118-degree drill point angle and 60-degree included countersink angle are standard for most fastener-prep applications. Right-hand cutting direction. Sold individually.

This combo drill countersink is suited for metalworking applications where a pilot hole and countersink must be produced in a single operation. Trade Size 4 makes it appropriate for common machine screw countersink work in steel, stainless, aluminum, and similar materials. It is typically used by machinists, tool-and-die workers, maintenance technicians, and fabricators working on production or repair drilling setups.

Key Features

• Cobalt construction resists heat buildup during high-speed or interrupted-cut drilling
• TiAlN finish extends tool life when cutting ferrous and hard alloy materials
• Combination design drills pilot hole and countersink in a single pass, reducing setup time
• 118-degree drill point angle suits general-purpose drilling in metal
• 60-degree included countersink angle conforms to standard flat-head fastener geometry
• Right-hand cutting direction for use in standard drill press or CNC spindle setups

Compatibility

Designed as an OEM-style replacement or direct-use tool for standard drill press, CNC, and hand-drill applications requiring a Trade Size 4 combination drill countersink in Series 0915.

Installation Notes

Installation and use should be performed by a qualified machinist or fabricator familiar with cutting tool setup and speeds. Secure the workpiece fully before starting the spindle. Use appropriate cutting fluid for the material being drilled to preserve tool life and surface finish. Inspect the tool for wear or chipping before each use and replace if the cutting edges show damage.
