Precision Twist Drill 015026 Hss Jobber Drill Bit 0.4130 in

Product Description

The PRECISION TWIST DRILL 015026 is a high-speed steel jobber length drill bit engineered for drilling into hard surfaces across a range of industrial and trade applications. Built to the R18 jobber length standard, this bit features a 0.4130-inch tip diameter and an overall length of 5.25 inches, with a depth of cut reaching 4 inches. HSS construction provides the hardness and heat resistance needed for sustained performance in ferrous metals, hardened plastics, and similarly demanding materials. Machinists, pipefitters, electricians, and general maintenance technicians reach for jobber length bits as a reliable, all-purpose drilling solution.

This bit fits standard drill chucks found on benchtop drill presses, handheld power drills, and magnetic base drills commonly used on job sites and in fabrication shops. The 4-inch depth of cut makes it well suited for through-hole drilling in structural steel, pipe flanges, electrical enclosures, and similar workpieces encountered in mechanical and electrical trade work. Its jobber length geometry balances reach and rigidity, reducing deflection during layout-critical drilling operations.

Key Features

• High-speed steel construction for durability in hard surface drilling
• 0.4130-inch tip diameter for precise, consistent hole sizing
• 4-inch depth of cut for through-hole work in thick stock
• 5.25-inch overall length following standard R18 jobber proportions
• Compatible with standard drill chucks on both handheld and bench-mounted equipment

Compatibility

Designed as an OEM-style replacement and general-use jobber length drill bit suitable for standard drill chucks across handheld power drills and drill press equipment used in mechanical, electrical, and fabrication trade applications.

Installation Notes

Installation is performed by trade professionals including machinists, pipefitters, and electricians using standard drill press or handheld drill equipment. Always secure the workpiece with appropriate clamping before drilling and confirm the chuck is tightened fully before operation. Use cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
