No need for deburring! For materials like brass, acrylic, and Jelacon! This ultra-hard drill, [Zero Bari], can drill straight while correcting even slightly bent pilot holes.
The "Zero Buri GK-HAZ" is a revolutionary hybrid drill that requires no deburring for aluminum and resin. It is a carbide drill that processes in one go without the need for a pilot hole, producing no burrs, and as long as there is no runout, the hole accuracy is below H6! With outstanding straightness, it can drill straight even with slightly bent pilot holes, and it is a jointly developed product with the Fukui Prefectural Industrial Technology Center, already patented! 【Cutting Examples】 ■ Aluminum 6063 (simultaneous drilling of double plates) ■ Acrylic (non-coated dry drilling) ■ Brass (non-coated dry drilling) ■ Delrin (non-coated dry drilling) ■ MC Nylon (non-coated dry drilling) ▶ Recommended Cutting Conditions Cutting speed V = 50 to 100 m/min Feed per revolution f = 0.041 mm/rev *For more details, please refer to the PDF document or feel free to contact us.

Applications/Examples of results
Please use this for drilling holes in aluminum, resin, brass, Duracon, acetate, and acrylic. It allows for clean drilling without burrs. 【Example】 Major aluminum processing company N ▶ Before drill change... Used high-speed drill (coated) from major drill manufacturer O. During processing, a lot of burrs occurred on the inside of the pipe. Many processes were required for burr inspection and removal. Drill lifespan, number of processed holes: 3,000 holes (with burrs). ▶ After drill change... After switching to Zero Burr GK-HAZ (DLC coated), both external and internal burrs were suppressed, eliminating the need for burr inspection and removal. The drill lifespan increased from 3,000 holes (with burrs) to 91,900 holes without burrs. The drill lifespan extended approximately 30 times. *For more details, please refer to the PDF document or feel free to contact us.

Company information
■Company Introduction Our company has been engaged in trial and error for many years to address one of the challenges in manufacturing: "deburring after drilling." We have finally succeeded in developing a mysterious drill that produces no burrs, called "Zero Burr." The Zero Burr is not just a tool for making holes; it is a carbide drill that can finish holes with high precision, free of burrs, and with true roundness and straightness. <Features of the Zero Burr Drill> ■ No burrs ■ No centering required ■ Can drill curved and angled holes in one shot ■ Hole accuracy H6~H7 ■ Surface roughness equivalent to spiral reamers ■ One-shot processing from centering to reamer finishing is possible ■ All series can be re-sharpened, etc... The number of steps in the drilling process is reduced, leading to cost reduction and increased productivity. We aim to be of service to our customers by understanding their needs and continuously challenging ourselves to create the best original tools, processing, re-sharpening, and coating until we achieve the optimal solution. While NC machines for cutting processes are becoming increasingly precise year by year, we aspire to be a consulting partner in searching for the "best processing methods" that can meet the various conditions intertwined with high precision.
