Precision Twist Drill 6000105 Spotting Drill 3/4 in Hss

Product Description

The PRECISION TWIST DRILL 6000105 is a 90-degree spotting drill designed to create precise center points and guide holes for follow-on drilling operations. Built from high speed steel with a bright, uncoated finish, it is suited for general-purpose metal-cutting applications where accurate hole location is critical. The drill features a 3/4-inch cutting diameter, a straight cylindrical shank, and an overall length of 8 inches. With a 90-degree point angle and spiral flute geometry, it produces clean, consistent spot marks that reduce drill walk and improve positional accuracy on machined parts.

This spotting drill is intended for use in machine shop environments, including CNC machining centers, knee mills, and drill presses. It is a single-ended, right-hand-cut tool appropriate for spotting operations on ferrous and non-ferrous metals in both production and job-shop settings. The SPR-90 series design targets general-purpose toolroom and manufacturing applications where consistent pilot geometry is required before reaming or tapping sequences.

Key Features

• 90-degree drill point angle for accurate, flat-bottomed spot starts that match standard drill point geometry
• 3/4-inch cutting diameter with matching 3/4-inch straight cylindrical shank for direct collet or chuck mounting
• High speed steel construction provides toughness and wear resistance across a range of workpiece materials
• Bright, uncoated finish compatible with a wide range of cutting fluids and coolants
• Two spiral flutes promote chip evacuation during spotting operations
• Right-hand cut, single-ended tool with 1-7/8-inch flute length for controlled depth engagement

Compatibility

Designed as a general-purpose spotting drill for use in standard 3/4-inch collet chucks or drill chucks on CNC machining centers, manual mills, and drill presses. Part of the PRECISION TWIST DRILL SPR-90 series.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the straight cylindrical shank firmly in a compatible collet or drill chuck before operation, and verify runout before beginning a cut. Power down and lock out the machine spindle before changing tooling. Do not exceed the recommended spindle speeds for high speed steel tooling in the applicable material, and apply cutting fluid appropriate to the workpiece material to extend tool life.
