BORE Jeweler's Drill Bit Master Kit With 300 HSS Twist Drills Sizes 51-80

The BORE Jeweler's Drill Bit Master Kit is a comprehensive drill bit storage and supply solution designed for professional jewelers who rely on precision HSS twist drills in small sizes. The kit combines 300 high-speed steel twist drills spanning 30 different sizes with a purpose-built 3D printed organizer from Nashef Designs, made in the USA.

The organizer features 32 compartments, each labeled with both wire gauge size (#51–#80) and millimeter equivalent (0.34mm–1.7mm), plus one unmarked compartment for mixed sizes and one closed compartment. A plastic-covered window on each compartment lets you see the contents at a glance, and the stepped floor design raises or lowers each compartment floor according to drill diameter — so even the smallest bits remain visible and accessible.

HSS Twist Drill Note: HSS twist drill shanks are the same diameter from tip to shank and become shorter in overall length as the diameter decreases.

Each kit includes 10 drills of each of the 30 sizes, ranging from size #51 (largest, 1.7mm / 0.0670") down to size #80 (smallest, 0.34mm / 0.0135"). As a bonus, every kit also includes one tube of Stay Sharp bur lubricant—the best-selling cutting lubricant in the jewelry industry.
