Milwaukee Tool Core Centering Pin for Thick Wall Core Bits

Milwaukee's 1-Piece carbide tipped core bits are ideal for drilling large holes where the depth is relatively shallow. The core bit cuts a kerf only. The inside core must be removed by the operator before deeper drilling can be accomplished. Use of centering bit 48-20-5495 is recommended (not included). Use drift key 48-20-5497 to remove centering bit from the 1-piece core bit. The 1-piece core bits are available in SDS-MAX or Spline shanks. They come in a variety of diameters ranging from 1-1/2 -inch to 6 -inch with overall lengths of 11-3/8 -inch or 22 -inch and a drilling depth of 3 -inch The asymmetric tooth pitch with alternating tooth geometries creates faster material pulverization. The 1-piece design maximizes energy transfer and the thick wall core body is durable even in large hammers. The fluted core exterior minimizes friction loss and removes debris faster. Use with SDS-MAX and Spline 1-Piece Core Bits to start drilling.

Milwaukee Tool 13-Inch Carbide SDS-PLUS Masonry Core Bit Adaptor

Milwaukee SDS-Plus Masonry Core Bits are ideal for drilling large holes in brick, block, and concrete with SDS-Plus rotary hammers. Asymmetrical carbide teeth break up material more effectively resulting in up to 20% faster drilling speeds. Centering bits allow for easy alignment of the hole and precise spot drilling. The versatile two-piece design allows users to drill with several different core bit sizes using one adapter. The spiral core body design minimizes friction in the hole and aids in dust removal during the application. Core bits cut with the outer edge only, therefore the operator must remove the inner core continue drilling for holes deeper than 3 inches.

Hilti 7/16 Inch X 12 Inch TE-CX SDS Plus Style Hammer Drill Bit

An X-shaped pointed tip and four cutting edges make this TE-CX masonry drill bit from Hilti a real workhorse. Its constructed with two-component tungsten carbide to absorb and withstand impacts with rebar when drilling into reinforced concrete, providing utmost strength and durability even as working temperatures escalate. The fluted design allows dust and debris to be rapidly expelled for steady performance when drilling into mortar, brick, cement, concrete, cinder block or other stonework. Its 10 mm shank fits SDS-Plus-style rotary hammer chucks.
