Precision Twist Drill 6000100 SPS-90 3/8 in HSS Short Length Spotting Drill

The Precision Twist Drill 6000100 is a SPS-90 Series Short Length Special Purpose Spotting Drill designed for accurately locating and starting holes in a wide range of materials. With a 3/8 in (0.375 in) body diameter and a 90° point angle, this spotting drill creates precise, clean entry points that guide standard twist drills and prevent walking or wandering on the workpiece surface.

Key Features:

• Series: SPS-90 Short Length Special Purpose Spotting Drill
• Diameter: 3/8 in (0.375 in)
• Overall Length (OAL): 3-1/8 in
• Flute Length: 1-1/8 in
• Point Angle: 90°, Conventional Point
• Flute Type: Spiral Flute
• Shank Type: Straight (Cylindrical) Shank
• Cutting Direction: Right Hand Cut
• Cutting Depth Ratio: 1×D
• Material: High Speed Steel (HSS)
• Finish/Coating: Bright (Uncoated) — improves chip flow in soft or non-ferrous materials

The bright (uncoated) finish is ideal for use in soft metals, aluminum, brass, and other non-ferrous materials, reducing built-up edge and promoting smooth chip evacuation. The medium-alloyed HSS construction delivers excellent hardness, toughness, and wear resistance, making it suitable for demanding production and job shop environments. The short overall length provides added rigidity and reduced deflection for greater accuracy.

Precision Twist Drill has been a trusted name in cutting tools since 1952, serving aerospace, automotive, and precision engineering industries. The SPS-90 spotting drill is an essential tool for any machinist looking to improve hole location accuracy and extend the life of their drilling tools.
