Volkel Tap Sets ISO 529 HSS-G - Large BSPF/NPT Special Sizes

Genuine VÖLKEL hand taps to ISO 529, HSS-G, for cutting internal G (BSPF) and NPT pipe threads in large and special sizes up to 2". Stocked by San Tools in the UAE for heavy-duty pipe fitting, hydraulic and pneumatic threading work.

Features

• ISO 529 Standard — standard hand tap geometry compatible with common tap wrenches and holders
• HSS-G Construction — ground high-speed steel for a sharp, long-lasting cutting edge
• G (BSPF) and NPT Thread Forms — covers both parallel BSP fitting threads and tapered NPT pipe threads
• Large Special Sizes — 3/4" through 2", beyond the standard tap set range
• Taper + Bottoming Combination — set of taps supplied together where applicable for a complete start-to-finish cut
• Straight Flute Design — reliable chip evacuation for large-diameter pipe tapping

How to Use

• Drill/Bore the Correct Size — use the correct pilot hole diameter for the large pipe thread you're cutting
• Use a Substantial Tap Wrench — large pipe taps need a wrench with enough leverage and grip for the torque involved
• Lubricate Heavily — apply plenty of cutting oil; large-diameter taps generate significant heat and friction
• Cut in Stages — advance a partial turn at a time, backing off to clear chips on these large threads
• Check Taper/Fit — test-fit a mating fitting periodically to confirm proper engagement
