Precision Twist Drill 010016 Hss Jobber Drill Bit 0.25in

Product Description

The PRECISION TWIST DRILL 010016 is a high-speed steel (HSS) jobber-series drill bit built for drilling into hard surfaces where heat and mechanical stress are constant concerns. With a 0.25-inch tip diameter and a 4-inch depth of cut, this bit is sized for a wide range of production and maintenance drilling tasks. HSS construction gives the cutting edge the hardness and heat resistance needed to maintain performance through repeated use in ferrous metals, hard plastics, and similar materials. Licensed trades and maintenance professionals reach for jobber-series bits when a standard, reliable drill geometry is required across varied workpieces.

This bit fits standard drilling applications in commercial and industrial maintenance, mechanical contracting, and fabrication environments. The jobber-length format is the most common drill bit configuration, making it compatible with most hand drills, drill presses, and magnetic-base drills used in the field. Its 0.25-inch diameter is a frequently used size for pilot holes, clearance holes, and anchor preparation across metal, mechanical, and structural work.

Key Features

• High-speed steel (HSS) construction for heat and wear resistance during hard-surface drilling
• Jobber-series geometry provides a balanced flute length suitable for general-purpose use
• 0.25-inch diameter tip for standard pilot and clearance hole applications
• 4-inch depth of cut accommodates typical through-hole and deep-hole tasks
• Sold individually, minimum order quantity of 1

Compatibility

Designed as a standard HSS jobber-length drill bit suitable for use with 3-jaw drill chucks accepting 0.25-inch round shanks, including most portable hand drills and bench-mounted drill presses used in trade and industrial settings.

Installation Notes

Drill bits of this type are installed and operated by electricians, plumbers, HVAC technicians, mechanical contractors, and general maintenance trades. Secure the workpiece before drilling and verify chuck tightness before operation. Use appropriate cutting fluid or lubricant when drilling through ferrous metals to extend bit life and reduce heat buildup. Wear appropriate eye protection in accordance with applicable jobsite safety requirements.
