Review: Great but, worked really well - I needed to drill some 1-1/2" holes in a cinder block retaining wall. I tried the diamond tip hole saws. Those were terrible. Kept binding, really slow cut. I kept the tool wet and it took over an hour to cut one hole. The holes was really clean and professional looking, but I was exhausted after just one. Switch to this guy and a cheap rotary hammer ($150 from a chain discount tool place), and I punched 10 holes in the same amount of time. I kept the tool wet so it would stay cool and keep a sharp edge longer. I was still pretty tired after an hour of work, but now I'm halfway done with the project. ## Features - UNIVERSAL: Fits all SDS-max hammers and Hilti hammers with TE-Y/TE-FY shanks - DURABLE: Solid carbide head is ideal for drilling masonry and concrete - RELIABLE: Stays sharper longer to drill more holes than competitors' bits - ACCURACY: Centric tip guides bit through hard and reinforced concrete - SPEED: Inclined side cutters have an aggressive edge for faster cutting ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000TZY2A | | Assembled Diameter | 1.5 Inches | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #20,854 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #12 in Rotary Hammer Drill Bits | | Brand | Bosch | | Color | Silver | | Customer Reviews | 4.7 4.7 out of 5 stars (1,838) | | Cutting Angle String | 120 Degrees | | Cutting Diameter | 1.5 Inches | | Date First Available | October 14, 2003 | | Finish | Uncoated | | Finish Type | Uncoated | | Global Trade Identification Number | 00000346208528 | | Included Components | 1-1/2 In. x 21 In.

I spent more on it because of the tungsten carbide tip but it was worth it. Drilled almost 20 holes 16” deep for using with Dexpan product (expansion grout for demolition) on some poured concrete stairs. There were a few times I hit metal in the concrete, but this bit went through it. The tip still looks great. Well worth the money. ## Frequently Bought Together - BOSCH HC5091 1-1/2 in. x 21 in.
