Magafor 80091503000 Combo Drill Countersink Size 3 Cobalt

Product Description

The MAGAFOR 80091503000 is a combination drill and countersink designed to drill a pilot hole and chamfer a seat in a single pass. Built from cobalt high-speed steel with a TiAlN coating, this tool handles harder workpiece materials and elevated cutting temperatures better than standard HSS tooling. It features a 118-degree drill point angle, a 60-degree included countersink angle, a 7/64-inch point diameter, and a 1/4-inch body diameter. Overall length is 2 inches. Right-hand cut geometry suits conventional drill press and CNC spindle rotation. Machinists, tool-and-die technicians, and fabricators reach for this type of combination tool when workflow requires countersinking without a secondary tool change.

This combo drill countersink is used in metalworking applications where a countersunk seat is needed for flat-head fasteners or deburring operations. The plain cutting edge style and right-hand cutting direction make it compatible with standard drilling setups. It is suited for production and job-shop environments working with steel, stainless, cast iron, and other ferrous materials where the cobalt substrate and TiAlN finish extend tool life under continuous cutting loads. The Series 0915 designation identifies it within the MAGAFOR product family.

Key Features

• Cobalt substrate for improved heat and wear resistance compared to standard HSS
• TiAlN coating extends tool life in ferrous and hard-material applications
• 118-degree drill point angle for general-purpose metal drilling
• 60-degree included countersink angle sized for standard flat-head fastener seats
• Right-hand cut, plain cutting edge style for use in conventional drill presses and CNC machines
• Combination drill-and-countersink profile eliminates a secondary tool change

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 1/4-inch shank drill press chucks and CNC tool holders requiring a Size 3 combo drill countersink.

Installation Notes

Installation is performed by machining professionals using a drill press, milling machine, or CNC machining center. Secure the tool firmly in a compatible chuck or collet rated for the shank diameter before operation. Always power down and lock out the spindle before changing tooling. Follow applicable shop safety standards and manufacturer feed-and-speed recommendations for the workpiece material.
