Precision Twist Drill 6000154 Spotting Drill 90 Deg

Product Description

The PRECISION TWIST DRILL 6000154 is a 90-degree spotting drill designed to create precise starter holes that guide larger twist drills and prevent walking on metal workpieces. Manufactured from high speed steel with a titanium nitride (TiN) finish, this single-ended drill delivers extended tool life and reduced friction in general-purpose drilling applications. It features a 5/8 inch cutting diameter, a 1.625 inch flute length, and an overall length of 4.375 inches. The two-flute spiral design promotes chip evacuation, and the straight-cylindrical shank seats securely in standard drill chucks and collet holders.

This spotting drill is suited for machine shop, fabrication, and production environments where accurate hole location is critical before drilling, countersinking, or tapping operations. The 90-degree point angle is a common standard that aligns with most countersink and center drill geometries used in metalworking setups. It is appropriate for use in CNC machining centers, knee mills, and drill presses operating on ferrous and non-ferrous metals. The Series SPSG-90 designation covers general-purpose spotting applications across a range of material types.

Key Features

• 90-degree drill point angle for accurate hole location and countersink compatibility
• High speed steel construction provides durability across general-purpose metalworking applications
• TiN coating reduces surface friction and extends cutting tool life
• Two-flute spiral geometry promotes efficient chip evacuation during spotting operations
• Straight-cylindrical shank fits standard drill chucks and ER collet systems
• Single-ended design with 4.375 inch overall length for use in standard toolholders

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and straight-shank collet holders accepting a 5/8 inch shank diameter, suitable for CNC and manual machine tool setups within the SPSG-90 series.

Installation Notes

Spotting drills are installed and serviced by machinists and toolroom technicians. Before inserting or removing the tool, ensure the machine spindle is fully stopped and locked out per applicable machine guarding procedures. Seat the straight-cylindrical shank fully into the chuck or collet holder and verify runout with a dial indicator before production use. Do not use this tool as a substitute for a center drill in applications requiring a 60-degree point angle, as point geometry is not interchangeable.
