HORUSDY 40-Piece SAE Tap and Die Set, Inch Sizes for Coarse and Fine Threads Tool with Storage Case
Industrial grade GCr15 bearing steel construction ensures durability and tool longevity to withstand professional uses. Suitable for cutting steel, copper, aluminum, cast iron and other materials..
Suitable for re-threading of fasteners and fastener holes, cutting or updating of internal and external threads. Precision milling of SAE taps and molds are used for cutting raw materials or repairing existing threads, removing screws, etc..
All cutting teeth are precisely CNC machined and accurately heat treated to Rockwell hardness 60 HRC for best threading performance..
Set includes (20) SAE Fractional taps and dies for coarse thread (UNC): 4-40 NC, 6-32 NC, 8-32 NC, 10-24 NC, 12- 24 NC, 1/4-20 NC, 5/16-18 NC, 3/8-16 NC, 7/16-14 NC, 1/2-13 NC.
(12) SAE Fractional taps and dies for fine thread (UNF): 10-32 NF, 1/4-28 NF, 5/16-24 NF, 3/8-24 NF, 7/16-20 NF, 1/2-20 NF.
Heavy-duty plastic suitcase, easy to transport, safe storage, quick to organize, prevent accessories from falling off..
★ Wide Application --- For threading through holes or shallow blind holes. 3 straight flutes design, rapid downward chip removal. Make new female threads or re-thread damaged female threads in stainless steel, ordinary steel, copper, aluminum, iron, alloy steel, plastic..
★ Machine Taps --- Machine taps are used in tapping machines, vertical drilling and milling machines. M1-M3.5 micro taps process wood and soft metals with lower hardness, mainly used in clocks and watches. Drill holes with a twist drill before tapping..
★ High Speed Steel --- The high speed steel tool has high hardness, high strength, good toughness, wear resistance, and heat resistance. Only the base substrate, without any additional coatings, good for a wide range of applications..
★ Useful Tips --- Control speed based on material hardness. Add appropriate tapping oil for higher quality internal threads and more durable taps. The tapping depth should not exceed 1.5 times the diameter (eg: diameter=6mm (M6), maximum tapping depth=9mm). The tapping angle should be 90 degrees vertical....
