Accupro A-6140070R Spotting Drill 0.7mm 2-flute Solid Carbide

Product Description

The ACCUPRO A-6140070R is a solid carbide spotting drill designed to create accurate starter holes for subsequent drilling operations. With a 120-degree drill point angle and a cutting diameter of 0.7mm (0.0276 inches), this tool establishes precise hole locations and reduces drill walk on both flat and curved workpiece surfaces. The 2-flute spiral flute geometry promotes clean chip evacuation in general-purpose applications. The bright/uncoated finish suits a wide range of common workpiece materials. At 30mm (1.1811 inches) overall length with a 1.5mm (0.0591-inch) straight-cylindrical shank, it is sized for small-hole work where positional accuracy is critical.

This spotting drill is suited for general-purpose machining environments including CNC machining centers, drill presses, and manual mills. It is intended for use by machinists and toolroom technicians working on precision components requiring tight hole-location tolerances. The short 2.4mm (0.0945-inch) flute length and rigid solid carbide construction make it well suited for applications where deflection and runout must be minimized before a larger drill or reamer follows.

Key Features

• 120-degree point angle for accurate spot location and reduced drill walk
• Solid carbide construction provides rigidity and tool life in general-purpose machining
• 0.7mm cutting diameter for fine, small-hole spotting applications
• 2-flute spiral flute design for efficient chip evacuation
• Bright/uncoated finish compatible with a broad range of workpiece materials
• Straight-cylindrical shank for straightforward collet or chuck mounting

Compatibility

Designed as a general-purpose spotting drill for use in standard straight-shank collets and chucks sized to accept a 1.5mm shank diameter on CNC or manual machine tools.

Installation Notes

Installation and use should be performed by qualified machinists familiar with small-diameter carbide tooling. Secure the straight-cylindrical shank in a properly sized collet or drill chuck, verifying minimal runout before operation, as carbide is brittle and sensitive to lateral loading. Ensure the spindle and workpiece are fully stopped before changing or inspecting the tool. Refer to machine tool manufacturer guidelines for appropriate feed rates and spindle speeds for carbide tooling at this diameter.
