Precision Twist Drill 6002745 Jobber Drill Bit Letter C

Product Description

The PRECISION TWIST DRILL 6002745 is a jobber-length drill bit in Letter C size (0.2420 inches diameter), ground from solid carbide and finished bright/uncoated. It features a 118-degree standard point angle with web thinning applied to reduce thrust and improve chip clearance at entry. The straight shank measures 0.2421 inches in diameter and 1.25 inches in length, while the overall length comes in at 3.25 inches. Two regular spiral flutes with a tapered web configuration channel chips efficiently during through-hole and blind-hole drilling operations. This bit is part of the Series D33F-D33W-D33L-D33M and is intended for use by machinists, maintenance technicians, and tool and die professionals.

This drill bit is designed primarily for drilling aluminum and non-ferrous materials, consistent with the workpiece material codes P, M, K, N, and H. It is suited for general-purpose applications in production, job-shop, and maintenance environments where a right-hand, regular spiral jobber bit is the standard tool of choice. The 2.0-inch flute length provides a maximum drilling depth of 2.0 inches, making it appropriate for a wide range of standard-depth hole applications in light-duty to medium-duty setups.

Key Features

• Solid carbide construction provides greater hardness and wear resistance compared to high-speed steel alternatives
• 118-degree standard point angle with web thinning reduces entry thrust and improves centering
• Regular spiral flute geometry at 8xD flute-to-diameter ratio promotes efficient chip evacuation
• Bright/uncoated finish compatible with a wide range of cutting fluids and dry-cutting scenarios
• Straight shank fits standard drill chucks without adapters
• Right-hand cut, two-flute design for conventional clockwise drilling operations

Compatibility

Designed as an OEM-style replacement or direct-use jobber-length drill bit within the PRECISION TWIST DRILL Series D33F-D33W-D33L-D33M product family, suitable for standard drill chucks accepting a 0.2421-inch straight shank.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician familiar with rotating cutting tools. Secure the straight shank fully in a properly sized drill chuck before operation and verify chuck tightness before applying feed pressure. Solid carbide tooling is brittle and susceptible to breakage from side loading or interrupted cuts — avoid lateral forces during drilling. Follow applicable shop safety standards and machine guarding requirements during use.
