Accupro 4500105 Jobber Drill Letter Y Solid Carbide

Product Description

The ACCUPRO 4500105 is a solid carbide jobber-length drill bit sized to letter Y (0.4040 inches) with a 140-degree point angle. Designed for demanding material removal in hardened workpieces, it features a TiAlN coating that extends tool life at elevated cutting temperatures. The slow spiral flute geometry promotes chip control in tough materials where standard flute designs struggle. A UR-thinned web reduces thrust requirements and improves center cutting performance. This drill is intended for use by machinists and tooling professionals in production or job-shop environments where carbide tooling is standard practice.

The 4500105 is suited for drilling hardened materials in precision machining applications. The straight cylindrical shank with a 0.5000-inch diameter seats in standard drill chucks or collet-style tool holders. With a flute-to-diameter ratio of 4xD, it handles moderate depth drilling without excessive deflection. The DIN specification designation ensures dimensional consistency for tooling setups that require standardized drill geometry. This bit is sold individually and is appropriate for both CNC and manual machine setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hardened material applications
• TiAlN coating provides thermal and oxidation resistance at high cutting speeds
• 140-degree proprietary point angle reduces thrust and improves entry in hard workpieces
• Slow spiral flute design promotes controlled chip evacuation in tough materials
• UR-thinned web for reduced drilling resistance and improved center cutting
• Straight cylindrical shank compatible with standard chucks and collet holders

Compatibility

Designed as a jobber-length carbide drill for use in hardened materials; fits any drill chuck or collet holder accepting a 0.5000-inch straight shank.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist following standard tooling practices. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the chuck or collet and verify runout before beginning a cut. Coolant-through capability is not present on this tool, so external coolant or cutting fluid application should be used where the workpiece material and machine setup allow.
