HI Q PARTS Center Driller

Jig for hand processing. It helps to drill a 1 mm diameter hole on the end face and side of the round bar. It corresponds to a round rod made of plastic of diameter 2, 3, 4, 5 mm. Core (end face) of plastic round bar material, jig for straight hole drilling on side surface. It is only for 1 mm diameter drill blade. If you want to open a hole smaller than 1 mm in diameter, please use a drill blade with a 1 mm millimeter axis and a small diameter blade at the tip (However, for the core / end face processing, the total length of the blade is 18 mm or more). ■ For high precision machining, also adjust the plaque itself to the specified size. Example: When using a 2.0 mm hole, allowable from 2.00 to 2.05 mm ■ At the first use, it is necessary to make holes for drill holes. By inserting a 1 mm size drill, it is possible to remove the extra plating thickness inside the drill hole. ■ Always use the specified size drill blade. The inner wall of the hole is scraped and the accuracy drops, the blade may not come off. ■ There may be scratches on the surface that are not problematic in use. Please note.
