Volkel Machine Taps DIN 5156 HSS-E Form C - NPT

Genuine VÖLKEL machine taps to DIN 5156, HSS-E, Form C for cutting internal NPT (National Pipe Taper) threads on CNC and manual milling/drilling machines. Stocked by San Tools in the UAE from 1/8" to 1" for pipe fitting, hydraulic and pneumatic threading on power tapping equipment.

Features

• DIN 5156 Standard — machine tap geometry for use in tapping heads, collet chucks and rigid tapping setups
• HSS-E (Cobalt) Construction — improved heat resistance and edge life over standard HSS, suited to steel and stainless
• Form C Chamfer — moderate lead-in for use in through holes and pipe fittings
• NPT Taper Thread Form — cuts tapered pipe threads for a pressure-tight seal in fitting work
• Size Range — 1/8" x 27 through 1" x 11.5 covers common plumbing, hydraulic and pneumatic sizes
• Machine Tap Shank — designed for power tapping on CNC mills, machining centres and tapping arms

How to Use

• Drill the Correct Tap Drill Size — use the correct pilot hole diameter for the NPT size you're cutting
• Use a Tapping Head or Rigid Tapping Cycle — set feed to match the taper and pitch of the fitting you're producing
• Run at the Recommended Speed — reduce speed on larger diameters and harder materials
• Flood or Mist Coolant — lubricate to extend tap life and improve thread finish
• Check Taper Fit — test-fit a mating fitting periodically to confirm proper taper engagement
