Accupro A-6140105R Spotting Drill 1.05mm 2-flute Carbide

Product Description

The ACCUPRO A-6140105R is a solid carbide spotting drill designed to create precise starter points for follow-on drilling operations. With a 120-degree drill point angle and a 1.05mm cutting diameter (0.0413 inches), it produces accurate center spots that guide larger drills and reduce walking on flat or curved workpiece surfaces. The two-flute spiral geometry promotes chip evacuation in tight entry conditions. At 30mm (1.1811 inches) overall length, the tool is sized for use in CNC machining centers, drill presses, and manual machines where compact reach is needed. It carries a bright, uncoated finish and is intended for general-purpose spotting in a wide range of materials.

This spotting drill is suited for machine shops, precision fabrication facilities, and toolroom environments handling small-diameter work. The straight-cylindrical shank seats cleanly in standard collet chucks or drill chucks sized for 1.5mm shank diameter (0.0591 inches). Single-ended construction keeps setup straightforward. Right-hand cut geometry matches conventional spindle rotation. Typical applications include pre-spotting holes before twist drilling, reaming, or tapping in production and prototype runs where positional accuracy matters.

Key Features

• 120-degree drill point angle for accurate hole spotting and reduced drill wander
• Solid carbide construction provides rigidity and wear resistance at small diameters
• 2-flute spiral design aids chip clearance during entry
• Bright, uncoated finish suitable for general-purpose materials
• Straight-cylindrical shank for secure seating in standard collet and drill chucks
• Right-hand cut for use with conventional spindle rotation

Compatibility

Designed as an OEM-style general-purpose spotting drill compatible with CNC and manual machine tool setups accepting a 1.5mm straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the tool from the chuck or collet. Verify collet or chuck bore matches the 1.5mm shank diameter before tightening to avoid runout. At small diameters, confirm runout with a test indicator before beginning production cuts to protect the tool from premature breakage.
