Pro Series Steam Tempered HSS Jobber Drills (Black Oxide) [Diameter: 1.0mm]

Professional Workshop Grade HSS Straight Shank Twist Drill

The Professional Workshop Grade HSS Straight Shank Twist Drill is a premium-quality general-purpose drilling solution engineered for maximum performance, durability, and precision in demanding workshop and industrial environments. Designed for professional tradespeople, machinists, engineers, and fabrication workshops, these drills deliver consistent cutting performance and long service life across a wide range of materials.

Manufactured from high-grade High-Speed Steel (HSS), these drills are built to withstand continuous use in professional applications where reliability and drilling accuracy are critical. The premium construction and precision ground geometry provide smooth cutting action, excellent chip evacuation, and dependable hole quality even under demanding operating conditions.

Sizes above 2mm feature a steam tempered black oxide finish that improves wear resistance, reduces friction, and assists with heat reduction during drilling. Sizes under 2mm utilise a bright finish for enhanced dimensional accuracy and precision small-hole performance. Together, these finishes help deliver the high level of consistency expected from a top-tier workshop-grade drill range.

Designed for use in portable drills, pedestal drills, drill presses, and CNC machinery, the straight shank configuration ensures secure clamping and stable drilling performance. Suitable for professional workshop use across a broad range of ferrous materials, these drills are built for reliability in both general engineering and industrial production environments.
