Precision Twist Drill 018049 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 018049 is a high-speed steel (HSS) jobber-length drill bit from the R18 series, designed for drilling into hard surfaces. Jobber-length geometry provides a balanced combination of reach and rigidity, making these bits a reliable choice for general-purpose metal drilling in shop and field environments. The HSS construction delivers the hardness and heat resistance needed to maintain a sharp cutting edge through ferrous metals, alloys, and similarly demanding materials. Machinists, pipefitters, ironworkers, and maintenance technicians are the typical end users of this type of bit.

This drill bit is suited for use in drill presses, hand drills, and magnetic base drills where a standard jobber-length bit is required. It is appropriate for production drilling, maintenance and repair operations, and fabrication work on hard metal surfaces. The Series 49 designation identifies the specific size within the PRECISION TWIST DRILL R18 HSS jobber line, making it straightforward to reorder the correct diameter for recurring applications.

Key Features

• High-speed steel (HSS) construction for durability on hard and ferrous surfaces
• Jobber-length design balances reach with bit stiffness to reduce deflection
• R18 series designation for consistent sizing and reordering
• Compatible with standard drill chucks used in hand drills and drill presses
• Sold individually (pack quantity of 1)

Compatibility

Designed as an OEM-style replacement and standard jobber-length HSS drill bit suitable for use with conventional 3-jaw drill chucks across hand drills, drill presses, and magnetic base drilling equipment.

Installation Notes

Drill bit installation and use should be performed by qualified machinists or trade professionals familiar with proper chuck-securing procedures. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before operation. Use appropriate cutting fluid when drilling hard metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
