Are you having trouble with burrs during processing? Let us introduce the mysterious drill that produces no burrs: the Zero Burr Drill X Series!

Introducing the revolutionary 【Zero Burr Drill X】 that suppresses burrs generated during drilling and machining of aluminum and molds. Are you experiencing excessive burrs on the backside of pipes that require a lot of manual work? The 【Zero Burr Drill X】 is a hybrid drill that combines a taper end mill and a reamer, capable of suppressing burrs that occur during drilling. By suppressing burrs from the outset, it leads to time savings, cost reductions, and lower labor costs. We have received many positive feedbacks from our customers who are using it. (See below) 【Features】 - No burrs produced - Capable of drilling curved surfaces and angled holes in one go - Hole accuracy H7 - Surface roughness equivalent to spiral reamers - Completes centering to reamer finishing in one drilling operation - Compatible with cross holes - Cutting conditions are 1.5 to 2 times that of Zero Burr two-flute drills - Equipped with oil holes We look forward to your inquiries.

"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.

The "GK-HCZ" Zero Burr Drill is a revolutionary hybrid drill that finishes everything from pilot hole processing to deburring and reaming in a single operation!

The Zero Burr Drill is a revolutionary hybrid drill that enables one-shot processing without a pilot hole, suppressing burrs and achieving hole accuracy of H6 or better. This is a case study of processing carbon fiber CFRP, which is considered difficult to machine. Carbon fiber tends to produce severe burrs, delamination, and chipping during processing, and the cutting tools also wear out quickly. By using the 'GK-HCZ', we can suppress burrs, delamination, and chipping, successfully achieving clean hole drilling with just one carbide drill! [Processing Case] ■ Tool Used: GK-HCZ DLC (Drill for CFRP) ■ Coating: DLC ■ Material: CFRP (Thermosetting Carbon Reinforced Plastic) ■ Cutting Conditions: S=2500 F=50 ■ Size: φ3.0 to φ12.0 ■ Regrindable Simultaneous drilling of CFRP and aluminum can also be done cleanly without delamination. Regrinding is possible, allowing for regeneration. *For more details, please refer to the PDF document or feel free to contact us.

With the super hard drill "Zero Bari Drill," you can drill through soft and easily meltable MC nylon without any burrs!

This is a case of perforating MC nylon using the ultra-hard drill "Zero Buri Fiber." MC nylon is prone to melting, and even with the zero burr drill (GK-HAZ) designed for aluminum and resin, fine burrs were generated. However, with the new product Zero Buri Fiber, there are truly zero burrs!! It is now possible to perforate even more cleanly and without burrs than before!! Material being processed: MC nylon Drill used: Zero Buri Fiber Model number: GK-HFBZ Although it has a special shape, it can also be re-sharpened, contributing to cost reduction for our customers. Additionally, while the Zero Buri Fiber was developed for CFRTP, it is also ideal for softer resins. Please give it a try.
