Value Collection SC1090032 Countersink 90 Deg 1 Flute Hss

Product Description

The VALUE COLLECTION SC1090032 is a single-flute, 90-degree countersink designed for deburring and chamfering operations in metal, wood, and composite materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool delivers reliable cutting performance in standard shop and field conditions. The 1/4-inch straight cylindrical shank seats securely in most drill press chucks and handheld power drill chuck jaws. With a 1/2-inch head diameter and a 45-degree centerline angle, it produces clean, consistent 90-degree countersunk seats suitable for flat-head fastener installations. A single flute design keeps construction simple and reduces clogging when working with softer materials.

This countersink is suited for use in fabrication shops, maintenance and repair operations, and general metalworking applications where a standard 90-degree countersink profile is required. It performs well in light-duty drilling setups and benchtop drill press use. The straight shank allows direct chuck mounting without an adapter, making it straightforward to deploy in residential and commercial MRO contexts. No pilot is included, so operators center the tool manually or use a fixture for precision work.

Key Features

• 90-degree included angle produces standard flat-head fastener seats
• Single-flute geometry reduces chip packing in softer workpiece materials
• High-speed steel construction handles steel, aluminum, wood, and plastics
• Bright, uncoated finish suits general-purpose applications without added cost

• 1/2-inch head diameter covers common countersink diameters for flat-head fasteners

Compatibility

Designed as a general-purpose OEM-style countersink for use in standard 1/4-inch straight-shank drill chucks found on benchtop drill presses and handheld power drills.

Installation Notes

A qualified machinist or maintenance technician should secure the shank fully in the chuck before operation and confirm the chuck key is removed prior to starting the spindle. Power down or unplug the drill press before changing tooling. Use appropriate cutting fluid or lubricant when countersinking ferrous metals to extend tool life. Eye protection is required during all cutting operations per standard shop safety practice.
