NACHI-FUJIKOSHI CORP.
Launched the Burrless Series, which eliminates the deburring process.
1.Our approach to the market trend
In 2018, we launched the Aqua REVO Drill, a new carbide drill with renewed materials, shapes and coatings.
In 2019, we launched the Aqua REVO Mill, a carbide end mill and afterward, expanded our tap lineup of "SG taps" and "Hyper Z taps"
as well to contribute to customers improving productivity and cost reduction.
Generally, in the cutting process, a rough edge or ridge, called a "burr", is generated on the edge of the part. Burrs have an adverse
effect on product quality and accuracy, which requires extra time and cost for a deburring process.
Utilizing the strengths of the technologies that we have cultivated so far, we developed the burrless series to minimize burrs andeliminate the deburring process. This has reversed the old concepts, “Burrs are highly likely to occur in the cutting process” and“deburring is necessary after the cutting”.
On December 21, 2023, a lineup of drills, taps, and end mills was launched simultaneously to improve user productivity dramatically.
2. Overview of new products(Combination of corner R and sharp edge)(1) Aqua REVO Drills Burrless① Features
The "C-point" is a new cutting edge design that reduces drill run-out. The "R-edge" reduces
the cutting resistance and the depth of cut to achieve minimal burrs when drilling through holes,
and eliminates the burrs remaining at the hole surface. Excellent burrless performance is demonstrated
even in cross-hole applications, which are difficult to deburr. Long life and stable cutting are also
realized under normal drilling conditions.
② Dimension range
Dimensions range: φ2.0 to φ16.0
Reference dimensions: Typical dimensions φ6.0 (Overall length 82mm)
11,700 yen/piece (excluding tax)

(Acute-angled edge with high centricity)(2) SG Spiral Taps Burrless① Features
The "S-edge", which cuts the bore diameter of the hole at the same time,eliminates burrs generated on the minor diameter of the internal thread.
In addition, the "G Chamfer" prevents the cutting edge from chipping throughimproved chip evacuation, which achieves the same tool life as general-purpose taps.

(Cut the bore diameter of the internal threadat the same time because root diameter is large.)② Dimension range
Dimensions: M3～M12 All 26 dimensions, coarse and fine thread for through and blind holes
Reference dimensions: Typical dimensions M6×1 (Overall length 62mm)
3,220 yen/piece (excluding tax)(3) Aqua REVO Mills Burrless① Features
The "W Helical" design, combines a right-hand helix cutting edge on thepoint, and a left hand helix cutting edge on the shank side of the tool tominimize the burr on the top and bottom surfaces when side milling.
In addition, the "C Chamfer", adopts a new shape at the cross section of the helical teeth
to suppress the risk of steps in the intersection area of the twisted cutting-edges.

(At the time of chamfering complete thread part,prevent the cutting edge from chipping.)(Good cutting balance, minimizing burron the top and bottom surface.)

Precision machining quality without burrs, and the same long tool life as normal products.
② Dimension range
4-Flutes 2.5D G
Dimensions range: φ6 to φ20
Reference dimensions: Typical dimensions φ10.0 (Overall length 70mm)
13,200 yen/piece (excluding tax)
3. Launch date and sales target
Launch date: December 21, 2023 worldwide release(Suppress the risk of steps in the intersection
area of the twisted cutting-edges)

Sales target: 300 million yen per year in the first year and 1 billion yen per year across the whole series in three years.
