Micro 100 QSPD-250-140X Spotting Drill 0.25in 140pt Carbide

Product Description

The MICRO 100 QSPD-250-140X is a solid carbide spotting drill designed to create accurate, centered starting points for follow-on drilling operations. Built to the QSPD series standard, it features a 140-degree point angle, a 0.25-inch cutting diameter, and a 2.5-inch overall length. The AlTiN coating improves heat resistance and tool life in ferrous and high-temp alloy applications. A web-thinned geometry reduces thrust load at entry. This tool is installed and used by machinists and CNC operators in precision manufacturing and job shop environments.

The QSPD-250-140X is suited for spotting and centering operations on CNC machining centers and manual mills where positional accuracy before drilling is critical. The Micro-Quik shank interface is designed for use with compatible quick-change tooling systems. The 140-degree point angle matches common drill geometry, reducing hole deviation on flat and angled surfaces. Right-hand cutting direction makes it compatible with standard spindle rotation. Typical applications include production machining of steel, stainless steel, cast iron, and similar materials.

Key Features

• 140-degree point angle matches standard twist drill geometry for accurate spot location
• Solid carbide construction provides rigidity and wear resistance in hard materials
• AlTiN coating extends tool life in ferrous metals and high-temperature alloys
• Web-thinned design reduces entry thrust and improves centering force
• Spiral flute, 2-flute configuration aids chip evacuation during spotting
• Micro-Quik shank for use with compatible quick-change toolholding systems

Compatibility

Designed for use with Micro-Quik compatible quick-change toolholding systems in CNC machining centers and manual milling machines requiring a 0.25-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping procedures. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Verify shank seating in the Micro-Quik toolholder before beginning any cutting operation. Follow applicable shop safety standards and machine manufacturer guidelines for tool runout and RPM limits.
