Drill Bit Set 4pcs L7A (0.8mm, 1.0mm, 1.5mm, 2.0mm)

Set of four Mineshima modeling drill bits

The set from the Japanese maker of modeling tools Mineshima contains four drill bits in diameters of 0.8 millimeters, 1.0 millimeters, 1.5 millimeters and 2.0 millimeters. That is a spacing which covers most ordinary work: from small holes for wires to seats for pins and tubes.

Why keep several diameters at hand

The most frequent reason a hole does not come out right is not a blunt bit but a wrongly chosen diameter. Anyone who has only one size available either widens the hole needlessly or forces a wire into it that does not belong there. A graded set also makes it possible to drill in stages, pre-drilling with a thinner bit and finishing with a thicker one, which is a markedly cleaner route with larger holes.

Tips for working with thin drill bits

• The thinnest diameters break most often: never pry sideways with them, as bending snaps the bit immediately.
• Clamp the bit with the shortest possible free length.
• Drill at a right angle and without pressure; the cutting work should come from the turning, not from your hand.
• A broken tip in a hole can be picked out of plastic with the point of a needle; in metal it is a problem, so work with feel.

Who the set is for

• Beginning modelers putting together their first kit of tools.
• Builders who want the basic diameters together in one package.
• Anyone adding holes for wiring, pins and tubes.

The drill bits have sharp tips. Store them out of the reach of children and protect your eyes while drilling.
