I hope this message finds you well. I recently purchased a small drill sharpening machine from your company and I must say, it has exceeded my expectations! We are truly satisfied with its performance and the quality of sharpening it provides. It has been a valuable asset in our workshop, effectively sharpening numerous drills with ease. I am reaching out because I would like to order a new sharpening stone for this machine. Could you please provide me with the part number for the appropriate stone? This will help me ensure I'm getting the right product for my needs. Thank you in advance for your assistance! Looking forward to your prompt response.
