Drills bits are cutting tools used to remove material to create holes, almost always of circular cross-section. Drills come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the chuck.
SDS plus drill bits are used for drilling into hard materials such as brick and concrete with minimal effort. The SDS part refers to the shank type, which has two sets of grooves that snap into the chuck making it more secure and allowing the bit to slide up and down giving you the hammer action.These bits are interchangeable with SDS drill bits and are available in a variety of sizes. As they are thinner, they are ideal for smaller holes.
SDS max drill bit is intended to drill larger holes and work in more extreme conditions. It is a drill bit that offers higher speed and drills with more power. It is therefore ideal for drilling on hard surfaces and for drilling larger holes.These bits have three open grooves, with a locking segment attached to the grooves rather than locking balls. They are made for bigger hammer drills and make bigger holes. SDS Max chisels are also available that can be used for chipping, digging, chiselling, and other heavy-duty work.
Square drill bits are also called mortise bits, and the best ones fit universally in most mortising machines and drill presses that have hammering functions.
An SDS hex drill bit is, as its name suggests, a bit designed to be used with an SDS rotary hammer drill. The dual action of rotation coupled with proper hammering makes chiseling and drilling through hard materials much easier than with a standard drill bit. An SDS bit is quite different than a standard bit and is composed of five parts.
A chisel is a tool with a characteristically shaped cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power.The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it.
SDS plus chisel delivers clean and fast removal of wall and floor tiles. Self-sharpening spade body retains uniform thickness throughout its lifetime for consistently high removal rates. Angled cutting edge and self-sharpening design are for a long life and a 30%-higher material removal rate.
SDS max chisels are made from high grade, forged steel, providing up to 20% longer life. These chisels are specifically designed for SDS-Max rotary hammers and should be used in hammer only mode.
