Precision Twist Drill 6000150 Spotting Drill 3/8 in Hss Tin

Product Description

The PRECISION TWIST DRILL 6000150 is a 90-degree spotting drill designed to create accurate center marks and starting points for follow-on drilling operations. Manufactured from high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction at the cutting edge. The drill measures 3.125 inches overall length with a 1.125-inch flute length and a 0.375-inch straight cylindrical shank. The two-flute spiral design promotes chip clearance and consistent entry-angle accuracy. It is a single-ended, right-hand cut tool suited for general purpose metal fabrication and machining work.

This spotting drill is used in machine shop, production, and maintenance environments wherever a precise, flat-bottomed pilot spot is required before drilling, countersinking, or counterboring. The 90-degree point angle is a widely accepted standard for spotting operations on CNC machining centers, knee mills, and drill presses. It is appropriate for use on steel, aluminum, cast iron, and similar ferrous and non-ferrous materials in both job shop and production settings.

Key Features

• 90-degree drill point angle for standard spotting and center-marking applications
• High speed steel construction provides toughness across a broad range of workpiece materials
• TiN coating increases surface hardness and reduces built-up edge on the cutting faces
• Two spiral flutes promote chip evacuation and stable cutting action
• Straight cylindrical shank fits standard drill chucks and collets without adapters
• Right-hand cut, single-ended design compatible with conventional spindle rotation

Compatibility

Designed as a general purpose spotting drill for use in standard drill chucks and collet systems accepting a 0.375-inch straight shank; part of the PRECISION TWIST DRILL SPSG-90 series.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist or toolroom technician. Secure the shank fully in a properly sized chuck or collet and verify runout before operation. Power down and de-energize the machine spindle before tool changes. Follow machine manufacturer guidelines for speed and feed selection appropriate to the workpiece material.
