Value Collection SC2090116 Countersink 90 Degree 6 Flute

Product Description

The VALUE COLLECTION SC2090116 is a single-end, 6-flute countersink designed for right-hand cutting in metal fabrication and machining applications. Built from high-speed steel with a bright, uncoated finish, this tool produces clean, chamfered seat profiles at a 90-degree included angle (45-degree centerline angle). The 1-1/4 inch head diameter and 3/4 inch straight-cylindrical shank make it compatible with standard drill press and milling machine setups. No pilot is included, and no separate countersink head is required. At 0.06 pounds, it is a lightweight but durable tool suited for general-purpose countersinking tasks in production and job-shop environments.

This countersink is appropriate for use on ferrous and non-ferrous metals where a 90-degree seat angle is required, such as when seating flat-head fasteners flush with a workpiece surface. It is commonly used in machine shops, metal fabrication facilities, and maintenance settings. The straight-cylindrical shank seats directly into a drill chuck or collet, eliminating the need for specialized toolholders. The 1-5/8 inch shank length provides adequate reach for standard depth countersinking without extended-reach tooling.

Key Features

• 90-degree included angle produces standard flat-head fastener seating geometry
• 6-flute design promotes smooth cutting action and reduced chatter
• High-speed steel construction handles a range of metal workpiece materials
• Bright, uncoated finish suits general-purpose machining without specialized surface treatment
• 3/4 inch straight-cylindrical shank fits standard drill chucks and collets
• Single-end configuration with no pilot included for operator-controlled hole alignment

Compatibility

Designed as a general-purpose countersink for use in standard drill press, milling machine, or lathe setups accepting a 3/4 inch straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by a qualified machinist or tooling technician. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Always power down and lock out the machine before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain finish quality.
