Value Collection SC10100040 Countersink 100 Deg Hss

Product Description

The VALUE COLLECTION SC10100040 is a single-flute countersink designed for creating conical recesses in metal, wood, and composite materials. Built from high-speed steel (HSS) with a bright uncoated finish, it operates with a 100-degree included angle and a 50-degree centerline angle. The straight-cylindrical shank measures 1/2 inch in diameter, and the head diameter is 5/8 inch. This tool is suited for machinists, fabricators, and maintenance technicians who require consistent countersink geometry without the added cost of a coated tool.

This countersink is intended for general countersinking applications in shop and field environments. The right-hand cutting direction makes it compatible with standard drill presses, CNC machines, and hand-held power drills running conventional forward rotation. The single-flute design provides smooth cutting action and is well-suited for softer metals, plastics, and wood where chatter control is a priority. No pilot is included, so the operator controls centering through fixturing or spotting.

Key Features

• 100-degree included angle for standard flat-head fastener seating
• Single flute design for smooth cutting and reduced chatter
• High-speed steel construction for durability across common workpiece materials
• Bright uncoated finish suitable for general-purpose use
• 1/2 inch straight-cylindrical shank fits standard drill chucks and collets
• Right-hand cutting direction compatible with conventional machine rotation

Compatibility

Designed as a general-purpose countersink for use in standard drill presses, CNC machining centers, and hand-held power drills accepting a 1/2 inch straight shank.

Installation Notes

A machinist or fabricator should secure the workpiece firmly before operation to maintain accurate countersink placement. Set spindle speed appropriate to the workpiece material and tool diameter before engaging the cut. Inspect the cutting edge for wear or chipping before each use, as a damaged single-flute tool will produce irregular seat geometry. Power down the machine completely before changing or seating the tool in the chuck or collet.
