Ruko HSS Core Drill Bit with 3/4 inch Weldon Shank, CBN Ground, Bright Finish, 38.0 mm Diameter, 88.0 Length, R108538

Ruko Hss Weldon 55 Mm Ø 38 Mm Hollow Drill Bit. RUKO HSS Weldon 55 mm Ø 38 mm Hollow Drill BitExperience unparalleled precision and efficiency in your metalworking projects with the RUKO HSS Weldon Hollow Drill Bit. Engineered for professionals who demand speed, accuracy, and durability, this 38 mm annular cutter is the ultimate solution for creating clean, perfectly sized holes with a cutting depth of up to 55 mm. As a leading product in the electric tool accessories category, this individual hollow drill bit, often referred to as a core drill, redefines performance standards for hole saws. Key Benefits:Achieve faster drilling times and superior results with this high-performance tool. Unlike traditional twist drills that must cut the entire diameter, this hollow drill bit only cuts the periphery of the hole, drastically reducing the amount of material removed. This core-drilling action requires less thrust and torque, resulting in significantly faster penetration rates and less wear on your drilling machine. The result is a smooth, burr-free hole with a precise finish, minimizing the need for secondary reaming or deburring operations. Its robust HSS construction ensures a long service life, even when working with demanding materials, providing an excellent return on investment through consistent and reliable performance. Main Features:This RUKO hollow drill bit is crafted for optimal functionality and resilience. The secure 19.0 mm Weldon shank provides a positive, non-slip drive by using flat surfaces that lock into the arbor, ensuring maximum torque transmission and preventing the bit from spinning in the chuck under heavy load. The precision-ground cutting edges are designed for aggressive yet smooth cutting action, while the optimized flute geometry facilitates excellent chip evacuation and allows for the efficient ejection of the core slug. The hollow design also enables internal cooling, allowing lubricant to be delivered directly to the cutting edge for reduced friction, lower heat build-up, and extended tool life. Application and Compatibility:This versatile hollow drill bit is specifically engineered for use in heavy-duty magnetic-stand and pillar drilling machines equipped with a morse taper retainer, making it an essential tool for fabrication shops, construction sites, and maintenance teams.For seamless integration with your equipment, this bit is compatible with:- RUKO arbor holders no. 108 302 / 108 303- RUKO EasyLock quick change system no. 108 312 / 108 313Upgrade your metal drilling operations with the precision and power of RUKO.---Technical Specifications:- Size (Diameter): 38.0 mm- Cutting Depth: 55.0 mm- Total Length (L1): 88.0 mm- Shank Type: Weldon shank- Shank Diameter: Ø 19.0 mm- Material: High-Speed Steel (HSS)- Cutting Direction: Right Hand Cut- Compatible Machines: RU25 / RU40- Weight: 0.22100 KG. tradeinn Bricoinn
