This is a set of round rods and a precision saw for filling and reinforcing screw holes in guitars, etc. Photo 2 shows an example of filling a neck hole with a 5mm rod. ＜Precision Saw＞ 　・This saw has fine teeth and a sharp cutting edge, as shown in the top photo. 　・Brand new and unused. 　・It is less likely to cause cracks in the cut material and less likely to scratch the body of the guitar, etc. (Please protect the surrounding area with masking tape, etc., just in case.) Round Rod Description 　・The description moves from the top to the bottom of the photo. 　・In addition to filling holes, it can also be used for reinforcement (e.g., the joint of a broken neck). ＜10mm Round Rod＞ 　・Made of high-strength beech wood. 　・Nominal diameter (diameter) 10mm / Length approx. 35mm / 4 pieces 　・Suitable size for re-drilling the anchor holes of Floyd Rose bridges. 　・Press-fit with a 10mm drill pilot hole, and the adhesive such as Titebond will get entangled in the spiral groove to bring out the bonding strength. 　・Since it is hard, carefully flatten the cut surface. ＜5mm Round Rod＞ 　・Made of ramin wood, which is also used for repairs by musical instrument stores. 　・Nominal diameter (diameter) 5mm (actual measurement: 4.8mm) / Length approx. 220mm / 2 pieces 　・Suitable size for filling neck mounting screw holes. 　・Adhere with a pilot hole of 5mm or more. ＜4mm Round Rod＞ 　・Made of ramin wood, which is also used for repairs by musical instrument stores. 　・Nominal diameter (diameter) 4mm / Length approx. 220mm / 2 pieces 　・Suitable size for filling the mounting screw holes of Strat-type tremolo units (bridges). 　・One 220mm rod can fill the 6 screw holes (depth: approx. 30mm) of the bridge. 　・Adhere with a pilot hole of 4mm or more.
