Featuring 100% carbide heads with a four-cutter design, these bits offer unmatched toughness and longevity, lasting up to five times longer than competing products. Bosch utilizes proprietary diffusion-bonding technology to bond carbide and steel at a molecular level, creating a solid-state weld that ensures jobsite-proven reliability. As the only concrete bit manufacturer to produce its own carbide, Bosch guarantees 100% quality control on every single bit. The four-cutter design provides a 180° cutting diameter and transfers 100% of the power during drilling for efficient performance. The active-centering tip produces rounder holes, while the four 90° side angles create a wide, sharp head that maintains precision. Additionally, the four-flute design aggressively removes dust from the work area, enabling faster drilling and extending the bit’s lifespan. \n\nModel Number:  Bosch 3\/4\" x 16\" x 21\" SDS-Max SpeedXtreme Rotary Hammer Drill Bit","brand":"Bosch","offers":[{"title":"Default Title","offer_id":46632334131363,"sku":"1362593","price":63.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/2469\/7763\/files\/8910c121e742c4455fdb67ed76e78ac0128c5ae8_1362593_1_H.png?v=1776151566","url":"https:\/\/www.hartvillehardware.com\/products\/bosch-3-4-x-16-x-21-sds-max-speedxtreme-rotary-hammer-drill-bit","provider":"Hartville Hardware","version":"1.0","type":"link"}
