Bosch PointTeQ High-Speed Steel Twist Drill Bit, 3.5 mm, Cylindrical Shank

The Bosch PointTeQ HSS Twist Drill Bit is a 1-piece high-speed steel twist drill bit. It is engineered for drilling through common ferrous materials, including steel and cast iron. The cutting end features a PointTeQ tip design that centres itself at the start of the cut. This self-centring action reduces the tendency for the bit to wander on smooth surfaces. Reliable hole starting helps users carry out workshop repairs, fabrication, and general metalwork with consistent results.

A 3.5 mm cylindrical shank provides a smooth, continuous gripping surface for standard drill chucks. The bit runs on standard right-hand rotation. This direction matches the majority of conventional handheld rotary drills and drivers. Its solid construction supports steady cutting as the bit progresses through dense materials. This structural stability helps maintain consistent power transfer from the drill to the workpiece.

• 3.5 mm cutting diameter sizes holes accurately for specific hardware installation and standard fastening.
• 135° tip geometry sets an effective cutting angle for typical metal drilling.
• 39 mm usable cutting length determines the maximum continuous hole depth into solid workpieces.
• 70 mm overall length provides adequate clearance when mounted in a handheld drill chuck.
• Open flute geometry promotes efficient chip removal and helps prevent displaced metal shavings from binding.
