Looking to make precise seats for your pavé-style settings? Busch® has formed a convenient 12-piece set which includes all that is needed to do this setting.
The set includes 6 Busch® 1AU Carbide Burs (one each of 010, 012, 014, 016, 018, 023), 4 Busch® 4205S Carbide Twist Drills (one each 007, 008, 009, 010) and finally 2 of the 231F and 231FL Circular Saws (0.2, 0.3 Diameter).
Your first step will be to create precise holes in your metal surface using a Busch® pavé twist drill. Due to its short working part, the 4205S Twist Drills produce uniform holes in very narrow spaces as necessary for tight pavé settings. Recommended speed: 3,000 - 5,000 rpm. Numerous holes can be drilled with constant precision after centering as these drills are made of the finest carbide.
The second step will be to round out the upper part of the seats with one of the 1AU round carbide burs. The carbide material will allow for longer life and consistency over standard steel burs thus producing a precise seat. Recommended speed: 2,000 - 10,000 rpm.
Finally, after completing steps one and two, it will be necessary to make a clean cross cut with a Busch® 231 F/FL Circular Saw. This will give you a clean and crisp space between the seats. You can choose the desired saw thickness to cut the desired notches for the stones. Recommended speed: 7,500 - 30,000 rpm.
All contents of the set are mounted on 3/32” shanks and are made of long-lasting carbide and thus will maintain their shape and sharpness for many uses, Items are also available separately and are made in Germany.
