Volkel Tap Sets ISO 529 HSS-G - Small Inch/Numbered Sizes (UNC/UNF)

Genuine VÖLKEL hand tap sets to ISO 529, HSS-G, for cutting internal UNC and UNF threads in small numbered sizes (No.4 to No.10) and 7/16"-9/16" sizes. Each set includes taper, plug and bottoming taps. Stocked by San Tools in the UAE for small-fastener and instrument work.

Features

• ISO 529 Standard — standard hand tap geometry compatible with common tap wrenches and holders
• Set of 3 Taps — taper (starting), plug (intermediate) and bottoming (finishing) taps in every set
• HSS-G Construction — ground high-speed steel for a sharp, long-lasting cutting edge
• UNC and UNF Thread Forms — covers both coarse and fine imperial thread series
• Small Numbered Sizes — No.4 through No.10 plus 7/16" and 9/16" for small fasteners and instrument work
• Straight Flute Design — good all-round chip evacuation for through and blind holes in general materials

How to Use

• Drill the Correct Tap Drill Size — use the correct pilot hole diameter for the numbered or fractional size you're cutting
• Use a Sensitive Tap Wrench — small numbered taps benefit from a light touch and low torque
• Start with the Taper Tap — its gradual chamfer starts the thread straight and true
• Progress to Plug, then Bottoming — use the plug tap to continue, and the bottoming tap to thread close to the bottom of blind holes
• Lubricate and Clear Chips — apply cutting oil and back off periodically to break and clear chips
