Harvey Tool 41016 Spotting Drill 0.25in 140deg Solid Carbide

Product Description

The HARVEY TOOL 41016 is a solid carbide spotting drill designed to create precise starting locations for subsequent drilling operations. Built to a 140-degree point angle with a Harvey Type II point geometry, it produces accurate, burr-free spot marks that guide twist drills and reduce walk on entry. The 0.25-inch cutting diameter and 0.75-inch flute length suit close-tolerance work in a range of metalworking applications. Right-hand cut with a spiral flute configuration, this tool runs on standard CNC machining centers and drill presses without special toolholding. Machinists and tool-and-die professionals working to tight positional tolerances rely on this style of drill as a first-operation tool.

The 41016 is suited for general-purpose spotting in ferrous and non-ferrous metals, plastics, and composites. Its bright, uncoated finish makes it compatible with a wide range of cutting fluids and does not require the elevated heat that some coated tools demand to activate lubricity. With a straight cylindrical shank at 0.25 inches diameter, it seats directly in standard collets, ER chucks, and drill chucks without adapters. Single-ended construction allows easy resharpening when edge life is exhausted.

Key Features

• 140-degree point angle with Harvey Type II geometry for accurate spot location and reduced drill walk
• Solid carbide construction provides rigidity and wear resistance across a broad range of workpiece materials
• Bright, uncoated finish compatible with flood coolant, mist, and dry-cut strategies
• 2-flute spiral design promotes chip evacuation from shallow spotting depths
• Straight cylindrical shank seats in standard collets and drill chucks without adapters
• Single-ended for simplified resharpening when needed

Compatibility

Designed as a general-purpose spotting drill compatible with standard 0.25-inch collets, ER chuck collets, and drill chucks on CNC machining centers and manual drill presses.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel. Power down and lock out the spindle before loading or removing the tool from the holder. Confirm the shank is fully seated and the collet nut or chuck is torqued to the toolholder manufacturer's specification before starting the spindle. Do not use spotting drills as center drills or for full-depth drilling beyond the stated flute length.
