DeWalt DW5537B25 Elite Series SDS PLUS Masonry Drill Bits 1/2 x 4 x 6

INCLUDES: 25 Drill Bits FEATURES: - Up to Two Times Longer Lifespan than BOSCH®*: The DEWALT ELITE SERIES™ 3/16” x 8” SDS PLUS drill bit DW5504 outlasts BOSCH® HCFC2012 when drilling C35/45 concrete. - Longer Life Compared to Previous DEWALT 4 - Cutter Design in C35 Concrete (Select Sizes)**: Our proprietary Circulating Cutting Carbide design provides more carbide surface area than the old 4 - cutter design. - Resistant to Rebar Strikes: Perfect for drilling holes in concrete. These bits are engineered to avoid breakage when hitting rebar. - No - Break Guarantee: If your drill bit fails for any reason while the anchor wear mark is still visible on the product head, DEWALT will replace it at no cost. - Reduces Breakage Risk: IRON BLAST TECHNOLOGY™ uses high - speed blasting to strengthen the bit and minimize the chance of breakage. - High - Speed Drilling: The 2 - Stage flute design with a variable helix pattern quickly clears debris from the contact area, speeding up the drilling process. - Anchor Wear Mark Indicator: Ensures accurate hole diameter when installing anchors. It's located on the carbide tip. Replace the bit when the wear mark fades for proper anchor installation. - Quick Starts and Precise Holes: Equipped with a full carbide pilot tip for fast starts and accurate hole positioning. SPECIFICATIONS: - Bit Diameter: 0.5 inches - Material: Carbide Tipped - Shank Style: SDS Plus With a lifespan up to twice that of BOSCH®*, the DEWALT ELITE SERIES(TM) SDS PLUS Drill Bit 3/16” x 8” can drill through tough concrete and handle rebar strikes. Select sizes have a longer lifespan than previous DEWALT designs due to the proprietary circulating cutting carbide design. Made in Germany with global materials, these bits are great for anchor installation. Strengthened by IRON BLAST TECHNOLOGY(TM), they resist fatigue and are extremely durable. DEWALT stands behind these bits with a NO BREAK GUARANTEE (see below). When you choose our bits, you have DEWALT's support.

Using these DeWalt drill bits is straightforward. First, make sure your drill is compatible with the SDS Plus shank style. Then, insert the bit into the drill chuck and tighten it properly. When starting to drill, apply a gentle pressure to let the full carbide pilot tip get an accurate start. As you drill, the 2 - stage flute design will quickly move the debris away, allowing for high - speed drilling. Remember to keep an eye on the anchor wear mark on the carbide tip. Once it's no longer visible, it's time to replace the bit for accurate anchor installation. When drilling, if you encounter rebar, don't worry too much as these bits are designed to resist breakage when striking rebar. But try to avoid continuous hard impacts to prolong the bit's life. For maintenance, after each use, clean the bit with a brush to remove any debris. You can also store the bits in a dry place to prevent rusting. If you follow these simple steps, your DeWalt drill bits will serve you well for a long time.
