Value Collection 91010 Spotting Drill 3/16 in Solid Carbide

Product Description

The VALUE COLLECTION 91010 is a solid carbide spotting drill designed to create accurate center indentations before full drilling operations. The 90-degree point angle produces a clean, precise start point that guides twist drills and prevents walking on flat or contoured workpiece surfaces. With a cutting diameter of 0.1875 inches (3/16 inches) and an overall length of 3 inches, this tool is well suited for CNC machining centers, drill presses, and manual milling setups where positional accuracy is critical. The bright, uncoated carbide construction is standard for general-purpose spotting work across a broad range of workpiece materials.

This spotting drill is used in machine shops, fabrication facilities, and production environments where controlled hole location is required before drilling, reaming, or tapping operations. The straight cylindrical shank seats directly into standard drill chucks and collet holders. Single-ended construction makes it straightforward to load and index in automated or manual tool-change setups. It is appropriate for use on ferrous and non-ferrous metals in general-purpose machining applications.

Key Features

• 90-degree drill point angle for accurate spotting and countersink-style entry
• Solid carbide construction for rigidity and wear resistance during spotting operations
• Bright/uncoated finish suitable for general-purpose use across common workpiece materials
• Two-flute spiral design with a 25-degree helix angle for efficient chip clearance
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction for conventional spindle rotation

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and collet holders accepting a 3/16-inch straight cylindrical shank on CNC machining centers, drill presses, and milling machines.

Installation Notes

Installation and operation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is de-energized before loading or removing the drill. Confirm the shank is fully seated and the collet or chuck is torqued to the tool-holder manufacturer specification before running. Inspect the cutting edges for chipping before each use, as carbide tooling can fracture if run in an improperly secured or misaligned setup.
