Tap FANAR M14x1.5 DIN-374C R45 (6H) HSSE-PM HL MASTERTAP D4-528M01-0145

FANAR M14x1.5 thread tap in DIN-374C R45 profile is a cutting tool for producing internal metric threads M14×1.5. Manufactured from HSSE-PM (high-speed steel with alloyed elements, powder metallurgy) and finished with a high-performance HL coating, this tap is intended for both machine and manual tapping where a DIN-374C R45 geometry and a 6H tolerance fit are required. The design targets consistent thread form, dimensional stability and wear resistance in metalworking operations including production, maintenance and repair.

Advantages

The HSSE-PM material provides improved hardness and toughness compared with conventional high-speed steels, supporting longer tool life under intermittent and continuous cutting. The HL coating reduces friction and increases surface durability, which helps to resist built-up edge and abrasion when cutting steel and alloyed materials. The DIN-374C R45 profile ensures a precise thread form while the 6H tolerance supports medium-fit assemblies. The geometry and finish are optimized for reliable chip formation and evacuation in typical tapping conditions.

Suitable for

• Cutting internal metric threads M14×1.5 in steel and alloyed metals
• Production runs on machine tapping centres and CNC equipment
• Manual tapping during maintenance, repair or assembly work
• Applications requiring DIN-374C R45 thread form with 6H tolerance

• Thread form: DIN-374C, R45
• Tolerance class: 6H (medium fit)
• Material: HSSE-PM (powder metallurgy high-speed steel)
• Coating: HL surface treatment for reduced friction and increased wear resistance
• Use: Suitable for manual and machine tapping

How to use

Select the correct pilot hole diameter and ensure the workpiece is securely clamped. For machine tapping, set appropriate spindle speed and feed to match material and tap size; use rigid tapping or tapping heads where available. For manual tapping, use a suitable tap wrench, apply steady axial pressure and turn evenly, backing off periodically to break chips. Apply an appropriate cutting fluid to improve lubrication and chip evacuation. After tapping, inspect thread form and fit with gauges or mating parts to confirm compliance with DIN-374C R45 and 6H tolerance.

Usage recommendations

Use recommended pilot hole sizes and cutting parameters for M14×1.5 in the specific workpiece material; maintain consistent lubrication and clear chips frequently. For harder or abrasive materials consider reduced speed and increased coolant flow to extend tool life. Store the tap in a protective holder to prevent damage to the cutting edges and coating.
