Magafor 81154030000 Combo Drill Countersink Size 3 Hss

Product Description

The MAGAFOR 81154030000 is a combination drill and countersink tool designed for simultaneous drilling and countersinking in a single operation. Built from high-speed steel with a bright, uncoated finish, this Series 154 tool features a 1/4-inch body diameter and a 7/64-inch drill point. The 82-degree included angle produces a standard countersink profile suited to flat-head fastener seating. At 2 inches overall length, it is compact and well-suited for use in drill presses and CNC machining setups. Right-hand cutting direction with a plain cutting edge style ensures straightforward chip evacuation in typical ferrous and non-ferrous workpiece materials.

This combo drill countersink is used in fabrication, sheet metal, and general machining applications where a countersunk hole is required before fastener installation. The double-end style extends tool life by offering two usable ends. It is a practical choice for machinists, toolmakers, and maintenance technicians working in production or job-shop environments who need a reliable, no-frills countersinking solution in a compact package.

Installation Notes

This tool is installed and operated by machinists or toolroom technicians. Secure the shank firmly in the tool holder or chuck before operation and verify runout is within acceptable limits to prevent tip breakage. Always use appropriate cutting fluid or coolant for the workpiece material to maximize tool life. Do not exceed the tool manufacturer's recommended RPM range for the given material and point diameter.
