Carbide Spiral Up Cut Router Bit with 3/8 Shank Nano Blue Coating 2 Flute CNC Upcut Router Bit for Wood MDF Aluminum Carving Engraving CNC End Mill 3/8 Cut Diameter, 1-1/4 CL, 3" OVL

Precision Engineering: Our router bits are manufactured using advanced 5 axis CNC grinding machines imported from Germany, ensuring exceptional precision with H5-grade tolerances. This technology guarantees consistent accuracy and reliability across mass production, even given the intricate nature of router bit fabrication. Each tool is meticulously crafted to deliver flawless performance batch after batch. Exceptional Durability: Crafted from K30 carbide material with 12% cobalt content and a hardness rating of HRA95.3. these router bits offer outstanding wear resistance and structural strength. They maintain a sharp cutting edge over prolonged use, significantly reducing the risk of premature dulling or breakage—even under demanding working conditions. Compression Cutting Design: The unique spiral upcut geometry enables smooth and efficient upcut operations. Ideal for grooving, slotting, mortising, dadoing, and plunge cutting, this design ensures clean edges and superior surface quality on both the top and bottom of the workpiece, minimizing tear-out and secondary finishing. Nano Blue Coating: Enhanced with a specialized Nano Blue Coating, these bits exhibit extreme surface hardness and exceptional heat resistance. Combined with an ultra-fine carbide substrate that offers high bending and abrasion resistance, this coating makes the tool ideal for high-speed machining of hard materials while extending service life. Optimized Chip Evacuation: The large chip flute design facilitates smooth and efficient removal of chips, reducing heat buildup and preventing chip re-cutting. This results in a smoother workpiece surface, improved cutting efficiency, and enhanced overall finish quality. YFTOOL: We stand behind our products with 100% customer support.

• REFUSE TO WEAR OUT QUICKLY AND BROKE：K30 carbide raw material contains 12% cobalt, HRA95.3. this provides sufficient hardness and strength for the router bit, ensuring a high sharpness of the cutting edge without rapid dulling and broke
• SMOOTH AND CLEAN CUTTING EFFECT：upcut router bits is designed with a 27° helical angle for upcut to facilitate chip evacuation and prevent delamination and edge bursting at the top and bottom of the workpiece
• APPLICATION：Application: Plywood, Laminate, Melamine, MDF, Softwood, Hardwood, aluminum, Cast iron low hardness steel Birch and other high hardness woods Designed to cope with any high hardness wood long cutting life
• ACTUAL TEST OF ROUTER BIT:YFTOOL found that glue is the key reason for the increase in hardness of any wood materials, so we made special designs of raw materials and manufacturing processes for the spiral router bits.and got better test results
• SPECIFICATION: Nano Blue Coating 2 flute up cut spiral router bits 3/8 cut diameter, 1-1/4 inch cutting length, 3/8 shank,3in overall length, the 2 flute upcut end mill can be used on routers with 3/8" collet
