Larger in every respect than a standard no. 30-style handpiece, the Big Guy Handpiece features a gracefully contoured aluminum grip that provides greater control while being more comfortable to use. Its 3-jaw chuck will hold the tiniest wire gauge drill as well as other rotary tools with shanks up to 1/4" diameter (actual range: 0-6.5 mm), which is a wider range than similar handpieces. The Big Guy Handpiece is designed for use only with the Economy Flexshaft no. 236-971 (see related products below). Measures 6" long overall and is provided with a chuck key. Made in China.
