Precision Twist Drill 018008 Hss Jobber Length Drill Bit

Product Description

The PRECISION TWIST DRILL 018008 is a high-speed steel (HSS) jobber length drill bit sized at number 8. Designed for drilling into hard surfaces, this bit belongs to the R18 series, a line built for demanding metal-working and general-purpose drilling applications. The jobber length format provides a balanced reach-to-rigidity ratio suited for bench drilling, hand drilling, and CNC or drill-press work. Licensed trades and maintenance professionals rely on HSS construction for consistent performance in ferrous and non-ferrous metals, plastics, and hard composites. Sold individually per pack with a minimum order quantity of one.

This drill bit is appropriate for residential and commercial maintenance, fabrication shops, and mechanical service environments. Typical use cases include drilling clearance holes, pilot holes, and through-holes in steel plate, structural iron, aluminum, and similar hard materials. The number 8 wire gauge size makes it well suited for fastener clearance and tapping prep work across a range of trade applications including plumbing rough-in, electrical panel work, and HVAC sheet metal fabrication.
