Makita is the leading manufacturer of professional power tools on the market. Impact gold extreme Torsion technology is a unique design which focuses the force exerted on a regular screw bit away from the tip, meaning less chance of breakage during the most vigorous impact applications. The B-42226 is made from robust high strength tatara steel and when coupled with an impact driver, these shorter bits will allow for working and manoeuvring in narrower spaces. The B-42226 can last up to 10 times longer than a standard 50mm bit. The length between the bottom to the tip is 20mm shorter.
