Dormer A170 HS 1/2in Parallel Shank Drill 16.00mm OL:157mm WL:84mm | A17016.0

Dormer A17016.0 16.0mm HSS Reduced Shank (1/2") Metal Drill Bit – 157mm OAL

Dormer A17016.0 is a reduced shank HSS metal drill bit designed to produce a 16.0mm hole while fitting a 1/2" (parallel) chuck, making it a practical choice when you need a larger diameter in a conventional drill or drill press.

Built for general drilling duties, this A170-series bit features a steam oxide finish to help reduce material pick-up during cutting, supporting clean, controlled drilling across a range of common engineering and fabrication materials.

Key Features

• 16.0mm cutting diameter: Ideal for larger clearance holes and fabrication tasks where a standard 13mm chuck would be limiting.
• 1/2" reduced straight shank: Allows a large diameter drill to be clamped in conventional drill chucks and toolholding.
• HSS construction: Suitable for general-purpose metal drilling applications.
• 118° conventional point: Strong point geometry that can be re-ground when required.
• Steam oxide finish: Helps reduce workpiece material sticking to the cutting edge for smoother drilling.

Suitable applications

• General drilling in steels, stainless steels, cast irons and non-ferrous metals (using appropriate cutting speeds and coolant).
• Workshop drilling on pillar drills and engineering machines where a 1/2" shank is preferred.
• Site and maintenance work where a larger hole size is needed but the chuck capacity is limited.
