18th Fukui Prefecture Science and Academic Award Special Prize Winner!! Received the Prefectural Nobel Prize!

High efficiency! With just one super hard drill, you can achieve clean drilling without burrs! A hybrid drill for CFRTP (thermoplastic) with multifunctionality!

The "Zero Buri GK-HCTZ Series" is a hybrid drill for CFRTP (thermoplastic CFRP) that allows for one-shot drilling without a pilot hole, resulting in no burrs. It can drill straight even with slightly bent pilot holes, exhibiting excellent straightness. The large waveform effect minimizes heat to the extreme, achieving outstanding cutting performance. 【Features】 ▶ No need for deburring ▶ Regrindable ▶ Hole accuracy is H6 or better as long as there is no runout ▶ Excellent straightness ▶ R-blade with a special R shape that disperses cutting resistance, reduces heat, further minimizes burrs (delamination), and extends lifespan ▶ Taper end mill that eliminates fine burrs (delamination) ▶ Reamer shape that finishes the hole sides beautifully ▶ Capable of drilling straight even with slightly bent pilot holes ▶ Jointly developed with the Fukui Prefectural Industrial Technology Center; patent obtained ▶ Awarded the Kansai Monozukuri Shin Selection 2014 If you have any other concerns regarding drills, please feel free to consult us anytime. We look forward to your inquiries.

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.

No burrs with a single perforation without a pilot hole! Even with a slightly bent pilot hole, perforation can be done straight while correcting.

The "Zero Buri GK-HCZ Series" is a hybrid drill for CFRP that reduces burr removal work, enabling cost reduction and high-efficiency production. It suppresses heat with a wave effect, achieving excellent cutting performance. It has good bite and features composite R shinning for precise positioning. Additionally, it is economical as it can be re-sharpened. 【Features】 ■ No burrs produced with one-shot drilling without a pilot hole ■ Hole accuracy is H6 or below as long as there is no runout ■ Excellent straightness ■ Can drill straight while correcting even slightly bent pilot holes ■ Jointly developed with the Fukui Prefectural Industrial Technology Center *For more details, please refer to the PDF document or feel free to contact us.

If there are no burrs, the hole accuracy is below H6! It allows for good engagement and precise positioning with composite R finishing.

The product we handle, "Zero Buri GK-HCTZ," is a hybrid drill for CFRTP. The recommended cutting conditions are cutting speed V = 20 to 40 m/min and feed per revolution f = 0.02 mm/rev. *Wet and mist drilling. It allows for one-shot drilling without a pilot hole, producing no burrs, and as long as there is no runout, the hole accuracy is below H6. Additionally, the wavy shaped effect significantly reduces heat with a large waveform effect, achieving outstanding cutting performance. 【Features】 ■ Taper End Mill - A taper end mill that eliminates subtle burrs to achieve zero burrs. ■ Extreme Keeness Blade - A special R-shaped design that disperses cutting resistance, reduces heat, further minimizes burrs (delamination), and extends the lifespan of the R blade. ■ Special Waved Drill - A wavy drill that achieves hole accuracy below H6 with 1/4 of the cutting resistance, effectively minimizing burrs. *For more details, please refer to the PDF document or feel free to contact us.

Suppress heat with waveform effects and achieve outstanding cutting performance! Waveform drill that minimizes burrs finely.

The "Zero Bari GK-HCZ" we handle is a hybrid drill for drilling CFRP. It allows for one-shot drilling without a pilot hole, producing no burrs, and achieving hole accuracy of H6 or better as long as there is no runout! It also accommodates cross holes on the sides and can be re-sharpened, leading to cost reductions. When combined with aluminum, it can drill from both the aluminum side and the CFRP side. With excellent straightness, it can correct for slightly bent pilot holes while drilling straight. This product was developed in collaboration with the Fukui Prefectural Industrial Technology Center and is patented. 【Features】 ■ Ripple Shaped Effect - The wave effect suppresses heat and achieves outstanding cutting performance. ■ Extreme Keeness Blade - The special R shape disperses cutting resistance, reduces heat, and further minimizes burrs (delamination), extending the lifespan of the R blade. ■ Special Wave Drill - With cutting resistance reduced to 1/4, it achieves hole accuracy of H6 or better and minimizes burrs with its wave-shaped drill. Recommended cutting conditions are cutting speed V = 20-40 m/min and feed per revolution f = 0.02 mm/rev. *Dry drilling *For more details, please refer to the PDF document or feel free to contact us.
