RUKO Machine tap DIN 376B M16 x 2 mm, HSS-Co5, 6H

The RUKO Machine tap DIN 376B M16 x 2 mm is a straight-fluted, Form B machine tap designed for efficient creation of metric ISO threads in through-hole applications across a range of ferrous and non-ferrous materials

• HSS-Co5 for enhanced heat resistance
• Straight flutes, Form B geometry
• ISO2 (6H) tolerance for precision
• Shaft Ø 12 mm for secure holding

Consistent threads and material suitability for demanding parts

The combination of HSS-Co5 cutting material and the specified M16 x 2 mm geometry provides a reliable baseline for machining medium-strength components. The tool is suitable for machining unalloyed steels, alloyed steels up to 1000 N/mm², malleable iron and non-ferrous metals, which reduces the need for multiple specialised taps on the shop floor. The 6H tolerance (ISO2) ensures that threads meet common assembly specifications, supporting interchangeability and reducing inspection overhead.

Geometry and chip evacuation tailored for through threading

The Form B design with straight flutes and a dedicated shaving/chamfer relief for through threads gives controlled engagement when cutting full-length holes. Flank relief and a right-hand cutting orientation optimise load distribution along the flutes, improving stability during feeding and lowering the risk of thread distortion. These design choices translate into fewer reworks and steadier cycle times for repetitive production tasks.

Machine compatibility and process reliability

A shaft Ø 12 mm and the DIN 376B shank form provide robust clamping in standard collets and tool holders, supporting secure torque transfer and repeatable concentricity in automated machining centres. The nominal cutting direction (right-hand cutting) aligns with conventional spindle rotation, simplifying process setup. Using a tool with a harmonised material and tolerance specification reduces variation between batches, aiding quality control processes and operational predictability.

Practical application and upkeep in the workshop

This tap is manufactured for serial use in production and benefits from correct support: appropriate feed rates, sufficient coolant or lubricant and steady clamping are decisive for tool life. The shaved flanks assist in reducing friction and maintaining thread quality over longer runs; regular inspection of thread form and prompt replacement when wear appears preserves component tolerances. If clarification on machine parameters or material combinations is required, Metav’s advisors can provide guidance tailored to the production environment.
