A corded hammer drill next to a drill bit and a chuck key. A hammer drill, also known as a percussion drill or impact drill, is a power tool used chiefly for drilling in hard materials. [1] [2] It is a type of rotary drill with an impact mechanism that generates a hammering motion.
The rotary hammer (also known as a rotary hammer drill, roto hammer drill or masonry drill). Standard chucks and parallel-shank carbide-tipped drills have been largely superseded by SDS chucks and matching (spline shank) drills, that have been designed to better withstand and transmit the percussive forces. These bits are effective at ...
A rotary hammer, also called rotary hammer drill [1] is a power tool that can perform heavy-duty tasks such as drilling and chiseling hard materials. [2] It is similar to a hammer drill in that it also pounds the drill bit in and out while it is spinning. However, rotary hammers use a piston mechanism instead of a special clutch.
Masonry bits typically are used with a hammer drill, which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the drill bit tip, and the rotating flutes carry away the dust. Rotating the bit also brings the cutting edges onto a fresh portion of the hole bottom with every hammer blow.
The shortest SDS-plus masonry drill bits are about 110 mm overall length, and the longest 1500 mm. SDS-max is more common for larger rotary hammers and chipping guns, and common sizes start at 1 ⁄ 2 inch (13 mm) diameter up to 1 + 3 ⁄ 4 inches (44 mm) diameter. Standard lengths are 12 to 21 inches (300 to 530 mm).
The connection end size is also related to the breaking energy of the tool. For example, the Bosch and Hilti 12 lb (5.4 kg) tools both use SDS-max, while the Bosch, Hilti, and Makita 65 lb (29 kg) tools all use 1+1/8 in hex connection. See hammer drills for more on electropneumatic hammering.
The rotary force is transmitted through wedges that fit into two or three open grooves. The bit is free to move a short distance and the hammer action moves the bit up and down within the chuck. Two sprung balls fit into closed grooves, allowing movement whilst retaining the bit. There are four standard sizes with varying shank diameters: SDS Quick
