Sgs 57007 Combo Drill Countersink 1/8 in Solid Carbide

Product Description

The SGS 57007 is a combination drill and countersink designed for precision hole preparation and countersinking in a single operation. Built from solid carbide, this tool delivers consistent performance in ferrous and non-ferrous materials where accuracy and tool life matter. It features a 1/8 inch body diameter, a 3/64 inch drill point diameter, a 60-degree included angle, and a right-hand cut. The double-end configuration extends usable tool life by providing two cutting ends. Overall length is 1-1/2 inches. This is a Series 301 tool with a plain cutting edge style and a bright, uncoated finish suitable for general-purpose machining applications.

This combo drill countersink is used in metalworking, machining, and fabrication environments where center drilling and countersinking are required before turning, milling, or assembly operations. It is appropriate for use in manual and CNC machine tool setups. Machinists, tool-and-die makers, and precision fabricators working in production shops or job shops will find it suited to tasks requiring tight positional accuracy and a clean countersink profile.

Key Features

• Solid carbide construction for extended tool life and wear resistance
• Double-end design provides two usable cutting ends per tool
• 60-degree included angle for standard countersink profiles
• Right-hand cut with plain cutting edge style
• Bright, uncoated finish compatible with a wide range of cutting fluids
• Compact 1-1/2 inch overall length suits confined machine setups

Compatibility

Designed as an OEM-style replacement or standard tooling addition for machine tool spindles and collet systems accepting 1/8 inch shank combination drill countersinks.

Installation Notes

This tool is installed by a machinist or toolroom technician in a collet, drill chuck, or toolholder rated for the 1/8 inch shank diameter. Ensure the machine spindle is fully stopped and the tool is secured before beginning any operation. Use appropriate cutting fluid or coolant for the workpiece material to prevent heat buildup and premature tool wear. Inspect both cutting ends for chipping or wear before each use, as solid carbide is brittle and can fracture if subjected to lateral loading.
