Dormer Morse Taper Shank Reamer Bit 20 mm Diameter, HSS, Bright Blue Finish, 8 Flutes, 200mm Length B10120.0

The Dormer Morse Taper Shank Reamer Bit, model B10120.0, is engineered for high-precision metalworking and hole-finishing tasks where dimensional accuracy and excellent surface finish are critical. Designed with a Morse taper shank, this reamer bit ensures a secure fit for commonly used industrial machines, lowering the risk of slippage during heavy-duty operation.

Fabricated from premium high-speed steel (HSS), this tool offers outstanding resilience against wear, impact, and elevated temperatures, extending the service life and maintaining consistent results across sustained production cycles. A bright blue finish adds corrosion resistance and facilitates effective chip evacuation, supporting clean operation and precise tolerances.

This model features a robust 20 mm diameter with an overall length of 200 mm and an effective cut length of 100 mm - making it suitable for deep and precise reaming in a variety of setups. The eight-flute design provides a smooth, vibration-free cut and helps deliver superior surface finish within close tolerances, essential for high-quality joins and assemblies in metal components.

Applications extend to automotive component production, metal fabrication, aerospace parts manufacture, roofing installations, and general-purpose engineering. The tool excels in enlarging and finishing holes in materials such as plain carbon and alloy steels, wrought and cast aluminium, copper alloys, and cast iron. Its suitability across both hard and soft metals gives flexibility on the shop floor and in adaptable production environments.

Each Dormer B10120.0 reamer is a single-piece HSS construction, offering both strength and accuracy for repetitive industrial or manufacturing use. The Morse taper shank is trusted by machinists for reliability and easy interchange in machine arbors, while the 6 mm shank size further supports compatibility with a wide range of toolholders.

Engineered with user safety and ergonomics in mind, the lightweight construction (approximately 337.7 g) ensures operator comfort and control without sacrificing performance.

This reamer bit is a dependable solution for any technical requirement where high accuracy and finish are demanded, making it a staple for machine shops, OEMs, and repair professionals alike.
