Precision Twist Drill 010029 Hss Jobber Drill Bit 29/64 in

Product Description

The PRECISION TWIST DRILL 010029 is a high-speed steel jobber-length drill bit engineered for drilling into hard surfaces where heat buildup and cutting force are constant concerns. With a 29/64-inch tip diameter and a 4-inch depth of cut, this bit handles deeper holes in a single pass without the need for step drilling in many applications. Overall length is 5.625 inches. HSS construction gives the bit the hardness to cut ferrous metals, alloys, and other demanding materials while maintaining edge integrity under friction and load. Trades professionals who work through structural steel, plate, or hardened components reach for jobber-length bits like this one for their balance of reach and rigidity.

This drill bit is suited for metalworking applications in industrial, commercial, and heavy trade settings. It fits standard three-jaw drill chucks found on bench drill presses, magnetic base drills, and hand-held electric or pneumatic drills. The jobber-series length makes it a general-purpose workhorse for machinists, pipefitters, ironworkers, and maintenance mechanics who need consistent, repeatable hole quality in ferrous and non-ferrous materials.

Key Features

• High-speed steel construction resists heat and wear during aggressive cutting cycles
• 29/64-inch diameter tip for precise hole sizing without secondary reaming in many applications
• 4-inch depth of cut allows single-pass drilling in thicker stock
• 5.625-inch overall length fits standard jobber chuck capacities
• Jobber-series geometry balances rigidity and reach for general metalworking use

Compatibility

Designed as a standard jobber-length drill bit compatible with three-jaw drill chucks sized to accept a 29/64-inch shank on bench presses, drill stands, and handheld power drills.

Installation Notes

Secure the bit fully in the drill chuck and verify it runs true before beginning a cut. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life and prevent work hardening at the hole edge. Always clamp workpieces securely and follow applicable shop safety standards before drilling. Inspect the cutting edges before each use and replace the bit if chipping or blunting is detected.
