Constructed from a cobalt high-speed steel alloy, this bit offers exceptional heat resistance, allowing it to maintain its cutting edge in high-temperature applications where standard HSS bits would fail. This makes it the ideal choice for drilling into stainless steel, cast iron, and titanium. \n\nThe bit features a 135? split point that starts on contact without \"walking\" or skating, eliminating the need for a center punch and ensuring precise hole placement. A rigid, thick web helix design adds stability during tough applications and provides fast material removal. For enhanced grip in the drill chuck and reduced slippage under high torque, the 3\/16-inch shank features three flats.\u003c\/p\u003e\n\u003c\/section\u003e","brand":"Bosch","offers":[{"title":"Default Title","offer_id":44153724469341,"sku":"RBCO4139","price":25.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/1342\/3453\/files\/Bosch_3-16_in_Cobalt_SP_Jobber_Drill_Bit_CO4139._1.jpg?v=1769412173","url":"https:\/\/beavertools.com\/products\/co4139-bosch-3-16-in-cobalt-sp-jobber-drill-bit","provider":"Beaver Industrial Supply","version":"1.0","type":"link"}
