T ECHNICAL INFORMATION New Tool
For Models HK0500 83mm(3-1/4")
Description Power Scraper
174mm(6-7/8")
CONCEPTION AND MAIN APPLICATIONS
Model HK0500 exclusively for SDS-Plus Bit , developed for fine
chipping works, such as tearing up tiles, joints, and mortar in re-
construction sites.
We have put Motor laterally and made the Barrel thickness to be 468mm(18-1/2")
suitable for gripping so that tile tearing works may be easier. In
Chuck structure, one-touch sliding system has been applied, which
you can attach only by inserting Bit and searching grooves.
Moreover, your fingers will not be exhausted in continuous operations
owing to Large switch and Large D-shape handle. At the top end, a
very effective dust-proof cap with lip has been applied.
