Precision Twist Drill 018004 Hss Jobber Length Drill Bit

Product Description

The PRECISION TWIST DRILL 018004 is a high-speed steel (HSS) jobber-length drill bit designed for drilling into hard surfaces and general-purpose metalworking applications. Jobber-length geometry provides the standard flute-to-shank ratio that machinists and tradespeople rely on for balanced rigidity and chip clearance. HSS construction gives the bit heat resistance and edge retention suitable for production drilling in ferrous and non-ferrous materials. This bit ships as a single unit and is sized as a Number 4 drill. It is the type of tooling used by pipefitters, electricians, HVAC technicians, and general contractors for layout and fabrication tasks on the job site or in the shop.

This jobber-length drill bit is suited for light industrial and commercial applications where a standard-length HSS bit is required. Typical use cases include drilling pilot holes, clearance holes, and through-holes in mild steel, aluminum, brass, and similar materials. It performs well in both hand-held drills and drill press setups, making it a versatile option for trade professionals across multiple disciplines.

Key Features

• High-speed steel (HSS) construction for heat resistance and edge retention during drilling
• Jobber-length geometry balances rigidity with reach for general-purpose use
• Number 4 drill size for precise hole sizing in layout and fabrication work
• Suitable for ferrous and non-ferrous materials including steel, aluminum, and brass
• Compatible with standard hand-held drills and drill press chucks

Compatibility

Designed as a standard HSS jobber-length drill bit for use in conventional drill chucks across hand-held and stationary drill press equipment.

Installation Notes

This drill bit is installed and used by machinists, pipefitters, electricians, and general trade professionals. Secure the bit firmly in the chuck before use and verify the chuck is fully tightened. Use appropriate cutting fluid when drilling hard or thick ferrous materials to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if the edges show signs of chipping or excessive wear.
