Harvey Tool 988008 Spotting Drill 1/8 in 90 Deg Solid Carbide

Product Description

The HARVEY TOOL 988008 is a solid carbide spotting drill designed to create precise starter holes that guide twist drills, reamers, and other rotary cutting tools. Built with a 90-degree point angle and Harvey Type I point geometry, this tool seats accurately on flat and curved workpiece surfaces, reducing drill walk and improving hole-location accuracy. The 0.125-inch cutting diameter and spiral flute design promote clean chip evacuation during spotting operations. At 3 inches overall length with a 0.375-inch flute length, it is sized for tight-clearance setups on CNC machining centers and manual knee mills alike. Licensed machinists and CNC operators install this tool as a first-operation step before finish drilling.

This spotting drill is suited for general-purpose spotting operations in ferrous and non-ferrous materials. The bright uncoated finish makes it a versatile choice when coolant compatibility with coated tools is a concern. Its 0.125-inch straight cylindrical shank seats directly into standard collet chucks and drill chucks without adapters, making it accessible across a wide range of machine setups. It is a single-ended, right-hand-cut tool intended for conventional clockwise spindle rotation.

Key Features

• 90-degree drill point angle for accurate spot location and reduced drill walk
• Harvey Type I point geometry for consistent seating on flat and contoured surfaces
• Solid carbide construction for rigidity and wear resistance in general-purpose machining
• Spiral flutes with 2-flute configuration for efficient chip evacuation
• Bright uncoated finish compatible with a wide range of cutting fluids and materials
• Straight cylindrical shank fits standard collet and drill chuck toolholders

Compatibility

Designed as a general-purpose spotting drill compatible with CNC machining centers and manual mills using standard collet chucks or drill chucks that accept a 0.125-inch straight cylindrical shank.

Installation Notes

Installation and operation of this tool should be performed by a qualified machinist or CNC operator. Power down the spindle and confirm zero RPM before installing or removing the tool from the chuck. Verify collet or chuck runout is within acceptable tolerance before use, as excessive runout at this diameter can cause premature tool breakage. Follow machine manufacturer guidelines for feed rate and spindle speed selection appropriate to the workpiece material.
