Tork Craft 5-Piece Hex Shank HSS Half Ground Drill Bit Set (1.5mm – 5mm) – NR05005-1

Upgrade your drilling speed and precision with the Tork Craft 5-Piece Hex Shank HSS Half Ground Drill Bit Set (NR05005-1). Featuring quick-change hexagonal shanks and 135° split points, this essential set includes the most popular micro-drilling sizes from 1.5 mm up to 5 mm for rapid, slip-free cutting in metal, wood, and plastic.

Key Features:

• Quick-Change Hex Shank: Standard 1/4" hex base locks securely into impact drivers and bit holders, preventing bit slip and accelerating task changes.

• 135° Split Point Tip: Self-centering point prevents bit "walking" across smooth metal or plastic surfaces, eliminating the need for center punching.

• Half-Ground HSS Construction: Half-ground flutes provide keen cutting edges and efficient chip clearance in non-ferrous metals, steel, and timber.

• Polished Friction-Reducing Finish: Bright polished finish minimizes friction and heat buildup to extend cutting-edge service life.

• Essential 5-Piece Size Range: Features 1.5 mm, 2.5 mm, 3 mm, 4 mm, and 5 mm bits—ideal for screw pilot holes, pop rivets, and electrical enclosures.

Detailed Description:

The Tork Craft NR05005-1 5-Piece HSS Drill Bit Set is designed for electricians, automotive technicians, and woodworkers seeking fast, accurate holes without bit slippage. Constructed from High-Speed Steel (HSS) with a half-ground flute profile, these bits deliver clean, burr-free penetration across soft-to-medium metals, mild steel sheet, hardwoods, and acrylics.

Unlike traditional round-shank drill bits that can spin inside keyless chucks under heavy load, the integrated hex shank provides positive drive engagement in cordless impact drivers, quick-change adaptors, and standard 3-jaw drill chucks. Whether drilling pilot holes for fine woodworking or installing fasteners in sheet metal, this compact set provides the torque transfer and durability needed for accurate daily work.
