先端交換式ドリル
A Replaceable Tip Drill (RTD) is an advanced type of drilling tool that features a detachable cutting tip, which can be replaced when worn out or damaged. This design allows for the cutting edge of the drill to be easily swapped out, without the need to replace the entire drill body.
- High efficiency modular drill
- Low drag design for superior hole accuracy
- Large core thickness to minimize flexural deformation
- Smooth deep hole machining due to finely chopped chips
- Simple tip replacement
Key features of replaceable tip drill
See clearly replaceable tip drill machining
Replaceable tip drill can reach 7-10 grade hole accuracy, can process 15*D depth, symmetrical design can greatly improve the processing efficiency, is 3-4 times more than the ordinary U-drill.Replaceable tip drill replaceable drill bit design, when the use of the drill bit wear and tear can also be repeated 2-3 times to repair and sharpening, greatly increase the economy.
ONMY Tools Exchangeable tip drills
Low resistance design realizes excellent hole machining accuracy and 4 features solve hole machining problems for high efficiency machining.
1. Low drag design realizes improved hole machining accuracy

The special S-curve cutting edge reduces cutting resistance and suppresses vibration during tool insertion.
2. Large core thickness of the shank to suppress twisting and deformation
20% increase in core thickness compared to other companies’ A, suppressing torsional deformation and improving hole accuracy
Cutting conditions: Vc=120 m/min, f=0.25 mm/rev machining diameter ø14,/D=5, machining depth 45 mm, Wet Material to be cut: S50C
Cutting conditions: Vc=120 m/min, f=0.3 mm/rev machining diameter ø14,/D=5, machining depth 55 mm, Wet Material to be cut: S50C
3. Excellent chip evacuation even in deep hole machining due to fine cut-off chips
Extended auxiliary slots (5D, 8D) on the rear face of the toolholder ensure smooth chip evacuation.
Cutting conditions: Vc=60 m/min, f=0.2 mm/rev machining diameter ø14,/D=5, machining depth 70 mm, Wet Material to be cut: SUS304
4. simple drill tip replace
