Industrial Rotary Hammer Drills
Rotary hammer drills are an important tool for anyone that has big projects ahead of them. With the capability of drilling large holes, chisel tough materials, and power through tough conditions, the hammer drill is a must-have. With many different parts, brands, and options to choose from, finding the right rotary hammer can be a daunting venture.What are the primary uses of a rotary hammer drill?
A hammer drill has plenty of power. For this reason, it has uses that primarily involve heavy and dense materials, such as:
- Drilling through masonry such as concrete or brick.
- Drilling thick woods and knots.
- Doweling to allow insertion of rebar, anchor rods, and pins, especially in concrete.
- Chip and hammer masonry for demolition
There are many brands to choose from when selecting a hammer drill. Here are some of the most common:
SDS refers to a chuck system and is short for slotted drive system. Rotary hammers use bits that slide into the chuck system for enhanced hammer ability and torque.
- SDS rotary hammers have bits that slide into a pair of grooves. They use 10-millimeter shanks to hammer and drill.
- SDS-plus rotary hammers have 4 grooves into which the bit slides. They are capable of using standard SDS bits as well.
- SDS-max is a heavy duty rotary hammer. It features an 18-millimeter shank that is inserted 90-millimeter into the chuck itself.
- Spline is an additional style of rotary hammer. It is a heavy-duty rotary hammer, similar to the SDS-max and compatible with that system.
Aside from brand and chuck type, other factors can influence your purchase. Here are some common things to consider.
- Rotary drills are big and heavy tools, and adding a battery in the case of a cordless drill will increase the weight. Drills using brushless motors can reduce the weight.
- Variable speed dials allow a user to control the speed of the drill. These dials are useful if you are drilling into wood products as wood needs a higher speed.
- Voltage ratings, which help determine the projects the drill can take on. Cordless drills also will note battery voltage.
- Kickback protection to help keep the tool in place and prevent kickbacks from damaging the equipment or the users hands or body.
- Handle position and ergonomics.
