It features a solid head carbide design that delivers up to 5x longer life and integrated rebar guards for maximum durability in hard aggregate. The 4-cutter geometry prevents lock-up in rebar to reduce downtime, while a sharp centering tip ensures exact spot drilling. Optimized variable flutes remove dust faster to reduce heat and improve cordless efficiency by delivering up to 15% more holes per battery charge. The bit has a 1-3\/8 inch diameter, an overall length of 23 inches, and an 18-inch usable drilling depth. It also includes a wear mark indicator to signal when the bit no longer meets ANSI B212.15 requirements\u003c\/p\u003e","brand":"Milwaukee","offers":[{"title":"Default Title","offer_id":45714013454522,"sku":"1002314574","price":129.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0739\/1530\/2074\/files\/1002314574_ai.jpg?v=1773783431","url":"https:\/\/www.loopstone.net\/products\/milwaukee-1-3-8-in-x-23-in-mx4-4-cutter-sds-max-carbide-drill-bit","provider":"Loopstone Store","version":"1.0","type":"link"}
