Testimonials

“I really appreciate the extra mile you guys are going to make sure your customers are satisfied. I have a degree in business and I've studied all that stuff about how companies are doing their best to keep their customer satisfied through marketing and incentives, but I can't think of another company (in any field) that makes me as satisfied as you guys do. I'm sure there are some places that sell materials here in Japan, but even with extra cost of shipping and customs fee, I prefer to buy from LMI, because I can trust LMI's service and quality of materials. No marketing and incentives can match the solid good service and I'm a very happy LMI customer.”

Tuning Machine Roller Hole Step Drill

HHSS with closeup of brad point and long spurs.

High speed steel step drill for Schallers™, Gotohs™ or any machine with a 10mm (3/8") barrel. For quick and correct fitting of classical guitar tuning machines, the holes that accept the string rollers should be slightly relieved where the roller passes through the outside rib of the guitar head. These custom-made step drills drill relieved holes in one operation, increase accuracy of hole placement, and clear chips quickly.

  • Short length, high speed steel
  • Brad-point style with long spurs
    (Very sharp, protected with hot dip plastic)
  • Black oxide finish
  • Outside diameter = shank size 
DIMENSIONS:
  • 27/64" OD, .402" D x 15/16" L step. 1/2" overall length.
  • For all Schaller™ classical machines or
    any roller of approximately .393" (10mm) diameter.
