Emuge EFUT3100.0635 Spotting Drill 0.25in 90deg Solid Carbide

Product Description

The EMUGE EFUT3100.0635 is a solid carbide spotting drill designed to create precise starter holes that guide twist drills, reamers, and other rotary cutting tools. Featuring a 90-degree point angle and a 0.25-inch cutting diameter, this tool establishes accurate center locations and reduces drill walk on flat, angled, or curved workpiece surfaces. At 2.5 inches overall length with a 0.75-inch flute length, it is compact and rigid enough for use in CNC machining centers and manual drill presses alike. The bright, uncoated finish suits general-purpose applications across a range of ferrous and non-ferrous materials. Machinists and tool-and-die professionals are the primary installers.

This spotting drill is suited for general-purpose machining operations in job shop, production, and maintenance environments. The single-ended, straight cylindrical shank mates directly with standard collet chucks, end mill holders, and drill chucks without additional adapters. The spiral two-flute geometry promotes chip evacuation during the short spotting cycle. Applications include pre-spotting before deep-hole drilling, countersink location marking, and center-point establishment on parts requiring tight positional tolerances.

Key Features

• 90-degree point angle for accurate drill location and reduced drill walk
• Solid carbide construction provides rigidity and wear resistance versus high-speed steel alternatives
• Bright uncoated finish allows direct visual inspection of cutting edge condition
• Two spiral flutes support chip clearance during spotting operations
• Straight cylindrical shank fits standard collet and drill chuck toolholders without modification
• Single-ended design for straightforward tool change and measurement

Compatibility

Designed as an OEM-style general-purpose spotting drill from the EMUGE EFUT3100 series, compatible with standard 0.25-inch straight-shank toolholding systems on CNC machining centers and manual drill presses.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Secure the shank fully within the collet or chuck to the recommended gauge-line depth before tightening. Power down and lock out the machine spindle before loading or removing the tool. Verify runout with a dial indicator after clamping, as excessive runout accelerates edge wear and degrades spot accuracy.
