Accupro 89698765 Spotting Drill 0.4375 in 120 Pt Solid Carbide

Product Description

The ACCUPRO 89698765 is a solid carbide spotting drill designed to create precise, accurate starter holes for follow-on drilling operations. With a 0.4375 inch cutting diameter, a 120-degree point angle, and a 3 inch overall length, this tool delivers consistent center location and reduces drill walk on ferrous and non-ferrous materials. The bright, uncoated finish suits general-purpose shop use across a wide range of workpiece materials. Machinists and tool-and-die professionals rely on spotting drills like this to eliminate the need for center punching and to ensure follow-on twist drills engage at the correct location without deflection.

This spotting drill is suited for use in CNC machining centers, manual drill presses, and production turning applications where hole location accuracy is critical. Its 1.25 inch flute length provides adequate chip clearance for shallow spotting operations, and the straight cylindrical shank seats securely in standard drill chucks and collet holders. Single-ended construction means the tool is replaced rather than re-ground, keeping cycle times predictable. General-purpose classification makes it a practical stock item for job shops handling mixed-material work.

Key Features

• 120-degree point angle promotes accurate hole spotting and reduces lateral deflection on drill entry
• Solid carbide construction provides superior rigidity and wear resistance compared to high-speed steel alternatives
• Bright, uncoated finish suitable for dry cutting and use with water-soluble coolants on a variety of materials
• Straight cylindrical shank is compatible with standard drill chucks and ER-style collet holders
• Right-hand spiral flutes with two-flute design for efficient chip evacuation in shallow spotting cuts
• Single-ended design ensures consistent geometry throughout tool life

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and collet holders accepting a 0.4375 inch straight cylindrical shank. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with cutting tool safety practices. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool from the holder. Verify that the chuck or collet is properly torqued and that runout is within acceptable limits before beginning a spotting operation. Do not exceed the recommended feed and speed parameters for the workpiece material and machine setup.
