I'm reaching out to inquire about specific drill bit products that I'm interested in purchasing. I'm looking for bits with a half-inch shank and various cutting diameters, specifically in sizes that include 1/8, 2/8, and 3/8. It would be great to get the details on the availability of these items, including any options you might have regarding material types and coatings. Additionally, I would appreciate it if you could provide pricing information for the specified sizes and any bulk order discounts available. If you have technical specs, manufacturing tolerance details, or lead times for delivery, please include that as well. Looking forward to your prompt response so we can move forward effectively.
