Three processes in one, one-step operation, greatly saving processing steps, improving work efficiency, and providing accurate processing results.\u003c\/li\u003e\n\u003cli\u003eCombination tap drill bit is used to create threaded holes, great for situations where both drilling and tapping are required. Can process both through holes and blind holes. Suitable for aluminum, mould steel, stainless steel, bronze, hard plastics, etc..\u003c\/li\u003e\n\u003cli\u003eSelf-centering point, do not need assistant center drilling or center punching. 1\/4-inch hex shank can be used on power tools more easily and securely. A tapered end on hex shank can prevent excessive tapping. It exceeds the tap to prevent thread breakage from over-drilling.\u003c\/li\u003e\n\u003cli\u003eHSS6542 thread tap offers higher hardness due to the addition of 5% cobalt, excellent heat resistance to withstand higher operating temperatures, and improved wear resistance, making it more durable and long-lasting. Features the base substrate without any coatings, well suited for most general purpose tapping.\u003c\/li\u003e\n\u003cli\u003eWorks with drilling machines, tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps. Machine taps are suggested to be used with tap collets with overload protection.\u003c\/li\u003e\n\u003cli\u003eTips: Recommended feed rate: general steel: 6-15m\/min; harder steel: 5-10m\/min; stainless steel: 2-7m\/min; cast iron: 8-10m\/min. The torque caused by too fast feed speed is too large, which can easily cause the tap to break. Taps are prone to chipping or breaking due to speed overload or non-vertical tapping.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"uxcell","offers":[{"title":"Default Title","offer_id":48710249840889,"sku":"a24071200ux1502","price":24.0,"currency_code":"AUD","in_stock":true}],"url":"https:\/\/www.harfington.com\/en-au\/products\/p-1555175","provider":"Harfington","version":"1.0","type":"link"}
