Tap FANAR GWINTOWNIK M8 DIN-371C R15 (6HX) HSSE-PM TS 1400

FANAR GWINTOWNIK M8 DIN-371C R15 (6HX) HSSE-PM TS 1400 is a machine tap designed for cutting M8 metric internal threads. Built to DIN-371C form with an R15 chamfer and 6HX tolerance, the tap is manufactured from HSSE-PM (high-speed steel produced by powder metallurgy) to provide improved hardness and wear resistance during production and maintenance machining of through and blind holes in various metals.

Advantages

The HSSE-PM material offers enhanced toughness and edge retention compared with conventional high-speed steels, reducing premature wear when threading steels and alloyed materials. The DIN-371C form and R15 chamfer ensure controlled thread entry and gradual cutting action, which helps reduce tool load and improves thread quality. The 6HX tolerance provides a reliable, standard-fit internal thread suitable for general mechanical assemblies. The tap’s geometry and heat-treated steel construction support consistent performance in machine tapping operations.

Suitable for

• Cutting M8 metric internal threads in through holes and blind holes
• General metalworking and maintenance machining
• Producing threads in steel, alloy steels, and similar ferrous materials
• Machine tapping operations on lathes, milling machines, and tapping heads

Key specifications

• Thread size: M8 metric
• Form and chamfer: DIN-371C with R15 chamfer
• Tolerance class: 6HX (internal thread fit)
• Material: HSSE-PM (powder metallurgy high-speed steel)
• Intended hole types: through holes and blind holes

How to use

Secure the workpiece and ensure proper alignment for machine tapping. Select appropriate cutting speed and feed for the workpiece material and the HSSE-PM tap; follow machine tool manufacturer recommendations. Use suitable cutting fluid to improve tool life and chip evacuation. For blind holes, monitor depth and retract periodically to clear chips. Use the tap with compatible holders or collets and ensure steady machine feed to avoid tool breakage.

Usage recommendations

For best results, match spindle speed and feed to the workpiece material, apply continuous cutting fluid for cooling and chip control, and inspect threads after tapping to confirm dimensional accuracy. Replace the tap if signs of wear or chipping appear to maintain thread quality and prevent workpiece damage.
