Bosch HSS PointTeQ Twist Drill Bit 16 mm, 120/178 mm, 12 mm Cylindrical Shank

The Bosch HSS PointTeq Twist Drill Bit 16 mm (Cylindrical Shank) is a one-piece high-speed steel twist drill bit designed for drilling holes in metal. High-speed steel resists the heat and friction produced during routine work. Rated specifically for steel and cast iron, the bit delivers consistent material removal on demanding jobs. A 16 mm diameter makes it suitable for larger through-hole applications. Bosch’s PointTeq tip geometry locates quickly on contact, giving stability and reducing wandering at start-up.

A 12 mm cylindrical shank allows the bit to fit securely in standard rotary drills and drill drivers. Both corded and cordless power tools are supported, giving flexibility for workshop or site use. The flute design clears metal chips effectively as the bit penetrates the workpiece, keeping cutting performance consistent during prolonged drilling. A silver finish provides clear visual contrast against darker industrial materials, helping the operator monitor progress.

• 178 mm overall length provides practical reach for recessed or thicker metal workpieces.
• 120 mm working length sets the maximum depth achievable in a single pass.
• 135° point angle supports efficient surface penetration and direct material extraction.
• Two active cutting edges work with the tip geometry to speed up cutting.
• Right-hand rotation matches the forward drilling mode on conventional power drills.
