Magafor 84421254000 Countersink 1 in 90 Deg Cobalt Steel

Product Description

The MAGAFOR 84421254000 is a single-flute cobalt steel countersink designed for deburring and chamfering operations in metal fabrication and machining applications. It features a 90-degree included angle and a 1-inch head diameter, making it well suited for preparing holes to accept flat-head fasteners and creating clean, precise chamfers. The straight-cylindrical shank measures 0.5 inches in diameter for secure tool holder or chuck engagement. Cobalt construction provides elevated heat and wear resistance compared to standard high-speed steel, extending tool life in harder workpiece materials. This countersink is sized for cutting diameters from 0.125 inches up to 1 inch.

This countersink is used in machining shops, manufacturing facilities, and maintenance environments where ferrous and harder alloy materials require accurate countersinking. The single-flute design reduces chatter and produces a smooth finish on the chamfer seat. It is appropriate for use in drill presses, CNC machining centers, and manual milling setups where a straight-shank tool is accepted. Machinists, toolmakers, and maintenance technicians are the primary users of this tool.

Key Features

• 1-inch head diameter for full-size countersink seats
• 90-degree included angle for standard flat-head fastener seating
• Single-flute geometry minimizes chatter and improves surface finish
• Cobalt steel construction for enhanced heat and wear resistance
• Cutting diameter range: 0.125 inches to 1 inch
• Straight-cylindrical shank for direct chuck or tool holder mounting

Compatibility

Designed as an OEM-style single-flute countersink for use in standard drill press chucks, CNC tool holders, and milling machine setups accepting a 0.5-inch straight-cylindrical shank.

Installation Notes

Installation of this countersink should be performed by a qualified machinist or toolmaker. Secure the straight shank firmly in a compatible chuck or tool holder before operation and verify runout before cutting. Power down and lock out the machine before changing or adjusting the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain chamfer quality.
