Three-setting rotary hammers can drill, hammer drill, or move a chisel bit in a linear back-and-forth motion (obviously, never attempt to use a chisel in either hammer drill or drill mode and never use a drill bit in chisel mode). Two-setting rotary hammers can drill (in wood or steel) or drill with hammer action. Rotary hammers have two or three settings. If it doesn’t seat, turn the bit slightly (in either direction) until it does. You simply line a modern SDS bit up with the drill’s chuck and insert it. The Americanized version of the acronym remains the same (SDS) but is understood to mean Spline Drive System or Slotted Drive System, perhaps a better description of these bits and how they are held in the chuck, not by tightening but by the slot on the end of the bit. Drill Faster and Easier With Diablo’s Stepped Bits.If, in the course of the same job, you need to punch a hole in masonry, just pop the drill bit out of your impact driver and chuck it into your hammer drill. There are better and faster ways to drill steel, and even wood, but you’ll find that an impact driver works well with these bits to make small-diameter holes in thin material. You can use them to make holes wood of any thickness, but I’ve found them to be not particularly effective in thick steel I limit their use to light-gauge metal, no more than approximately 3⁄16-inch thick. Keep in mind that these bits are jacks of all trades but masters of none they allow you to switch quickly between drilling in a variety of materials and driving fasteners in those same materials. Chuck these multi-material bits into a hammer drill instead to make a hole in brick, concrete, concrete block, mortar, or stone. Note: Don’t use your impact driver to make holes in masonry, which could burn it out. To use them in a drill driver, you tighten the chuck on them as you would a bit with a round shank. To use them in an impact driver, you insert them as you would any other hex shank bit. I employ them in my hammer drill but also in my impact driver. I own a set of them and find them indispensable for making holes in wood, concrete, brick, and mortar. One example is the MP500 bits from Bosch. They are most commonly used to drill in wood and masonry. *Output and performance will vary depending on cycle rate, viscosity of the grout mixture and pressure conditions.There are multi-material bits that can drill in all common construction materials except for glass. Placement Hose Size: 1-1/2″ ID by 60″ long, Clear Vinyl *Output Capacity: 6 gallons/minute (48 cu. Pump Type: Single Diaphragm, Self-Priming Pumps most types of cementitious grout (not for epoxy-type grouts) Makes an ideal tool for placing grout anywhere that high pressure is not required. Easy to operate, minimal maintenance required. Hand operated no electric or air power source needed. Used to form clean-out covers for High Lift grouting.
