Colt & Riss Zero Mark Countersink Bits

Colt Tools and RISS were manufacturers of high-quality boring bits with facilities in Germany and France. They made the popular MaxiCut and Ecocut forstner bits and Twinland brad point bits. Colt and Riss recently closed its doors and liquidated its inventory. We acquired a portion of this inventory and are offering it for a fraction of the list price. Quantities are limited to stock on hand.  

Specifications:

• Laser etched scale allows precise countersink depth setting

• Rotating depth stop body stops turning on contact with the work piece to prevent marring
• High carbon steel countersink cutter allows independent adjustment of the pilot drill bit depth
• 1/4 inch hex shaft is quick change compatible
