Precision Twist Drill 6000116 SPSG-120 3/4 x 5 120-Degree TiN HSS Spotting Drill Bit

The Precision Twist Drill 6000116 is a SPSG-120 Series 3/4" diameter × 5" overall length spotting drill bit engineered for accurate hole location and chamfering in a wide range of materials. Featuring a 120° point angle and a Titanium Nitride (TiN) coating over a High Speed Steel (HSS) body, this spotting drill delivers extended tool life and reduced friction compared to uncoated alternatives.

Key Features:

• Series: SPSG-120 Spotting Drill
• Diameter: 3/4" (0.750")
• Overall Length: 5"
• Point Angle: 120° — ideal for creating precise cone-shaped starter holes that guide follow-up drill bits
• Coating: Titanium Nitride (TiN) — improves surface hardness, reduces heat buildup, and extends tool life
• Material: High Speed Steel (HSS)
• Shank: Straight shank — same diameter as the drill body for easy chuck mounting
• Usable Depth: Suitable for drilling to a depth of up to 1× the tool diameter
• Compatible Materials: Performs across a broad range of metals and synthetic materials, with optimal results in steel, copper, aluminum, and magnesium

Precision Twist Drill has been a trusted name in precision cutting tools since 1952, serving aerospace, automotive, and general machining industries. The SPSG-120 spotting drill is designed to eliminate drill walk, improve hole positional accuracy, and create clean entry points for follow-up drilling operations.
