Milwaukee Electric Tool Corporation, which calls itself "an industry-leading manufacturer and marketer of heavy-duty, portable electric power tools and accessories for professional users worldwide," manufactures the Kango hammer drill. If you purchase a Kango directly from the manufacturer or from a reputable used power tool company, and you know how to use it, there is no bad Kango hammer. Milwaukee's best Kango hammers are the Kango 545 S and the Kango 500 S, which they have sold since 2007.
Most Powerful Drill
The Kango hammer is a 5kg-class combination and chiselling hammer. It is used for chiselling grooves into wall surfaces for electrical conduit or hold pipes, repairing brick walls, chiselling away old tiles, removing concrete or mortar pieces, drilling through-holes for pipes or power cables and drilling holes for the installation of power junction sockets or boxes. Milwaukee claims that their Kango hammer, with a 1,300W motor, is the largest and most powerful drill on the market.
The electronics of the Kango hammer feature precise starting of drilling and/or chiselling, a lock-on function for fatigue-free, continuous operation, a Variolock chisel (able to be locked in twelve positions) and a safety clutch to protect both the user and the hammer if drill bits get jammed. Other safety features include an angled power cable that prevents breakage and a countersunk gear switch that protects against abrasion or collision. It delivers between twelve and fourteen joules of energy for fast penetration.
The Best Kangos
The main difference between the two Kango hammers Milwaukee manufactures is its handles. The straight handle of the Kango 545 S controls the high torque at drilling, while the spade handle of the Kango 500 S provides more control and grip at different chiselling positions and angles. Both hammers are easy to handle, even with gloves, because their large gear switch, speed switch and tool reception make for a good grip. When sensitive materials such as bricks, tiles and old walls are being drilled, drilling speed and blow energy can be reduced in the soft-hammer mode.
The Kango 950K
Milwaukee also sells an older model, the Kango 950K. It features a 21mm tool reception, a built-in motor level with the gear, alternating voltage, short delay of full-speed drilling, a precise drilling and chiselling start-up, and an automatic change in drilling speed in no-load situations depending upon the amount of pressure used. It has an all-metal gearcase, which enhances its service life, and can be turned and adjusted to angles up to 360 degrees, which makes for effective, ergonomic handling.
