Transforming the rotation of the motor into a hammering action, these little jackhammer handpieces are a wonder for riveting, stone setting, and texturing. The hammer handpiece delivers the power, allowing you to concentrate on accuracy. Each concentrated hammer blow is delivered at the end of an interchangeable “point,” or steel tip, which screws into the handpiece. Points come in a variety of shapes, including texturing tips, flat or domed points for general hammering and stone setting, and blanks designed to be easily modified.
You control the hammering speed (number of strikes per minute) through the foot pedal, and determine the strike force by a knurled adjustment wheel. Many brands have come and gone but the two main players are Foredom and Badeco. Points can be switched between brands.
The Foredom #15 is moderately priced at around $100 and well built: Overall, a good choice.
But ah, the Swiss! Great chocolate and sweet handpieces. The Badeco, more sturdily built and with a more adjustable range of hammer force, is more expensive, as much as double the price of its cousin. It’s a great choice for the pro or the full-time user.
