Quick change 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\u003e6542 (M2) high speed steel screw taps run at high speeds and generate threads quickly and efficiently, offering high hardness, wear resistance, and good toughness. Features the base substrate without any coatings, well suited for most general purpose tapping.\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":48472139628793,"sku":"a24071100ux1246","price":7.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/2477\/6095\/files\/ux_a24071100ux1246_ux_g03.jpg?v=1780366460","url":"https:\/\/www.harfington.com\/en-gb\/products\/p-1567517","provider":"Harfington","version":"1.0","type":"link"}
