We currently have a small line of metal drill bits (Link to Dremel Website) in our accessory range that we are looking at partially replacing with TiN coated versions. We would like to invite you to quote on this project. I have included technical information on the drill bit sizes that we currently sell – essentially we will just need TiN versions of these same sizes. In addition as you can see on the link to our website, we sell our current accessories with a small, simple plastic case. We do not need this exact storage solution but would like you to propose something similar. Our estimated sales volume is 30,000 pcs/year for the set. Additional Current Drill Bit Specs:• Material: GB W6Mo5Cr4V2 or SAE M2• Hardness: RC 62+/-2• Rust preventive included
