Teflon is a great product to add to your drill bits. The cost is minimal but the advantages are great. According to one test report we ran with a Canadian Research firm, Teflon drill bits, used in tandem with a vacuum system and a silicone spray unit, can increase your drilling life by 500%. That means instead of re-sharpening your bits every 4 hours you can extend their life to about 20 hours. This will great decrease down-time on long-run jobs. DHP was the first company to add Teflon to drill bits back in the 1980's. Please call if you would like to see a copy of the engineering report. A vacuum system and a silicone spray unit can be added to a Dexter-Lawson machine.
