- 【Advanced PVD Nano-Coating】- Our annular drill bits, already exceptional, are further enhanced with a CrAlTiSiXN PVD nano-coating. This ultra-thin 3-micron layer reduces friction for smoother, faster cutting, increasing speed by 50% while maintaining a fine finish. The coating also significantly boosts wear and heat resistance, extending tool life by up to 10 times. Ideal for heavy-duty tasks, it handles greater loads, making it perfect for rough machining large workpieces.
- 【Better Heat Resistance】- PVD-coated Annular Cutter excels in high-temperature machining environments and processes tough materials like titanium alloys. The coating's heat resistance preserves the cutting edge's hardness and sharpness, reducing wear from overheating. It also decreases friction and heat buildup during cutting, allowing the mag drill bit to withstand higher speeds while maintaining accuracy—perfect for high-efficiency machining, such as mass production and rapid prototyping.
- 【Clean & Crisp Cutting】- The KEENTECH annular cutter set with PVD Coating is ideal for precision machining environments where high accuracy and surface finish are critical, such as aerospace components or mold manufacturing. The PVD coating reduces surface defects, ensuring exceptional precision and a superior finish on the workpiece. It delivers stable cutting performance and minimizes surface flaws, producing smoother and more accurate holes compared to HSS or uncoated TCT annular cutters.
- 【Usage Instructions】 - First, ensure the two flats of the Weldon shank are aligned with the two screw holes during installation to maintain stable cutting. Second, use the recommended cutting fluid instead of water, choosing the right cutting fluid is crucial for extending the tool's life. Third, the correct RPM and feed rate can double your efficiency. Please refer to the RPM chart in the product description for the appropriate speed settings.
