"Zero Barrier fiber" can now be manufactured in non-standard thin diameters from φ1.0 and above!! A deburring drill specifically for resin, carbon fiber CFRP, CFRTP, and UD materials!
We are pleased to announce that our popular product, Zero Buri Fiber, is now available in a non-standard size starting from φ1.0! Previously, production began at φ3.0, but we have now eliminated burrs effectively using a fine-diameter carbide drill of φ1.0, allowing us to sell it as a special item! As you can see in the attached photo, even at a magnification of 50x, it is clear that the holes are cleanly drilled without any burrs. Please take a look at the comparisons with other companies. ▶ Usage: Zero Buri: GK-HFBZ Special Item ▶ Material being processed: PP ▶ Thickness: 5mm ▶ Cutting conditions: S=3350rpm, F=250mm/min ▶ Surface treatment: Non-coated ▶ Photo magnification: 50x ▶ Target materials: PP, MC Nylon, Duracon, PVC, resin, CFRTP, GFRTP, dedicated to UD materials Zero Buri Fiber can also be used for drilling with a drill press, so please take this opportunity to try it out. With just one Zero Buri, you can achieve such clean drilling without burrs.
High-grade center drill improved for mass production processing!
The HG center drill is a center drill improved for mass production processing. It achieves thorough improvements in takt time and stable lifespan. Particularly in small diameter sizes, it has several times the lifespan of conventional center drills. The carbide ALD coating type (TiAIN) features a fine particle carbide ALD coat for even longer life. It is also compatible with dry processing. The small diameters with cutting edge diameters of φ0.3mm-1.0mm are available in increments of 0.1mm. Additionally, the powder high-speed steel TiCN coating type allows for even higher speed processing and longer lifespan by applying TiCN coating to powder cobalt high-speed steel. For more details, please contact us or refer to the catalog.
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.
Adopting aluminum chromium nitride coating! Improved heat resistance, wear resistance, and anti-welding properties!
- The aluminum-chromium nitride coating prevents chip welding, excels in heat resistance and wear resistance, and maintains sharpness. - The adoption of a spiral shape sharpens the cutting angle significantly compared to straight grooves, greatly improving cutting performance. - The tip uses the same S-shaped thinning design as conventional products for excellent sharpness. - The shank is hexagonal, allowing for use with cordless drills. - It offers high durability performance even against difficult-to-cut materials like stainless steel (compared to our conventional products).
Recommended for drilling holes in two types of metal wires.
Drilling holes in two types of metal wires can be done with step drills, hole saws, or punchers, but the raceway drill was created to make the task easier. By incorporating stepped shapes of 8mm and 10mm during the transition from the 6mm tip to the maximum 12mm, cutting performance is improved. It allows for drilling 6mm and 12mm holes in a single operation, and it is also possible to deburr the backside of the 6mm through hole.
The "HT 800 WP" is a replaceable tip drill developed by a German global manufacturer with over 125 years of history, capable of processing holes up to Φ40.
The 'HT 800 WP' accommodates hole machining up to a maximum diameter of Φ40 with standard products, offering a variety of inserts and holders that support machining depths from 1xD to 10xD, tailored to the workpiece material. The inserts feature a special finish on the cutting edge, providing excellent wear resistance. The holders are designed with a size increment of 0.5mm, ensuring a robust design with high rigidity. The unique groove shape allows for optimal chip evacuation even in deep hole machining. By incorporating a coolant duct on the groove heel side, effective coolant supply to the cutting edge is made possible. *For more details, please refer to the cutting conditions table in the product catalog or feel free to contact us.
You don't need to remove that foundation.
The correction of the foundation's alignment and the adjustment of the excavation can be carried out without removing the foundation while keeping the anchor bolts in place.
