Value Collection SC2190116 Countersink 1-1/4 in 90 Deg 6 Flute

Product Description

The VALUE COLLECTION SC2190116 is a single-end cobalt steel countersink designed to create clean, accurately angled seat recesses for flathead fasteners in metal, hard plastics, and other demanding materials. It features a 90-degree included angle with a 45-degree centerline angle, a 1-1/4 inch head diameter, and 6 flutes for smooth chip evacuation and a fine surface finish. The straight-cylindrical shank measures 3/4 inch in diameter for secure chuck engagement. Cobalt steel construction provides elevated heat and wear resistance compared to standard high-speed steel, making it suitable for production environments and interrupted cuts.

This countersink is intended for metal fabrication, machine shops, and maintenance applications where consistent fastener seating is required. The right-hand cutting direction is compatible with standard drill press and CNC machining setups. With no pilot included, it is typically used in a drill press or milling machine with a work-holding fixture to maintain positional accuracy. It is sold as a single tool and is appropriate for both job-shop and production use.

Key Features

• 1-1/4 inch head diameter for large-diameter countersink applications
• 90-degree included angle suits standard flathead machine screw seating
• 6-flute design promotes smooth cutting action and quality surface finish
• Cobalt steel construction resists heat buildup during extended or high-speed use
• 3/4 inch straight-cylindrical shank fits standard drill chucks and collets
• Right-hand cut for use with conventional clockwise-rotation spindles

Compatibility

Designed as a general-purpose countersink for use in drill presses, milling machines, and CNC machining centers with a chuck or collet accepting a 3/4 inch straight shank.

Installation Notes

Installation and use should be performed by a qualified machinist or tool-and-die technician. Power down and lock out the spindle before securing or removing the tool from the chuck or collet. Use appropriate work-holding fixtures to prevent workpiece movement, as this tool does not include a pilot for self-centering. Follow shop safety standards and machine manufacturer guidelines for speed and feed selection when working with cobalt steel tooling.
