Value Collection 91020 Solid Carbide Spotting Drill 90 Deg

Product Description

The VALUE COLLECTION 91020 is a solid carbide spotting drill designed to create accurate starter holes for follow-on drilling operations. With a 90-degree drill point angle and a 0.25-inch cutting diameter, it precisely locates hole centers and reduces drill walk on flat or angled workpiece surfaces. The two-flute spiral design with a 25-degree helix angle promotes clean chip evacuation. At 3 inches overall length with a 0.75-inch flute length, this single-ended tool handles general-purpose spotting across a range of materials. A licensed machinist or tool-and-die technician is the typical installer in production and maintenance environments.

This spotting drill is suited for general-purpose machining applications in job shops, production facilities, and maintenance repair operations. It performs well when used prior to twist drill, reamer, or tap operations where precise hole location is critical. The straight cylindrical shank seats directly into standard collet chucks, drill chucks, or ER collet systems. Its bright uncoated finish makes it a cost-effective choice for use in aluminum, brass, mild steel, and similar materials where coated tooling is not required.

Key Features

• 90-degree drill point angle for accurate hole spotting and center location
• Solid carbide construction provides rigidity and wear resistance over high-speed steel alternatives
• Two-flute spiral design with 25-degree helix angle for efficient chip clearance
• Bright uncoated finish suits dry or light-coolant general-purpose machining
• Straight cylindrical shank compatible with standard collet and drill chuck systems
• Right-hand cutting direction for use with conventional CNC and manual spindle rotation

Compatibility

Designed as a general-purpose spotting drill for use in standard collet chucks, ER collet holders, or keyless drill chucks accepting a 0.25-inch straight cylindrical shank.

Installation Notes

Install and remove this tool only when the machine spindle is fully stopped and the machine is in a safe, locked-out state per applicable shop safety procedures. Seat the shank fully and evenly in the collet or chuck before tightening to the tool-holder manufacturer's specified torque. Use appropriate feeds and speeds for the workpiece material to prevent carbide chipping. Solid carbide tooling is brittle and should not be used in setups with excessive runout or workpiece movement.
