Description
The YG-1 Dream Drill 0081ATF is a stub-length, TiAlN-coated solid carbide drill engineered for precision and versatility in general-purpose metalworking.
Part of YG-1’s renowned Dream Drill General Series, this tool is optimized for steel, cast steel, cast iron, and malleable iron, delivering excellent accuracy and extended tool life.
Its R-thinning web ensures self-centering and effective chip control, while the wave-shaped cutting edge with negative land minimizes thrust force and torque.
The TiAlN coating allows for higher cutting speeds and heat resistance, making it ideal for both manual and CNC applications.
Key Features
- R-Thinned Web Design: Provides self-centering and prevents walking during entry.
- Wave-Shaped Cutting Edge: Low thrust and stable torque improve tool life and hole precision.
- Optimized Flute Geometry: Ensures smooth chip evacuation and maximum drill strength.
- TiAlN Coating: Excellent oxidation resistance for high-temperature applications.
- Stub (3×D) Length: Enhances rigidity for high-precision holes and reduced deflection.
Q1: What materials can the 0081ATF Dream Drill cut?
A: It’s optimized for steel, stainless steel, and cast iron. The TiAlN coating allows it to handle harder materials at higher speeds with consistent performance.
Q2: What does “stub length” (3×D) mean?
A: “3×D” indicates a flute length approximately three times the drill diameter, which provides greater rigidity, less deflection, and better positional accuracy — ideal for short-hole drilling.
Q3: What’s the benefit of the R-thinning design?
A: The R-thinned web helps self-center the drill, reduces thrust, and creates smaller, easily evacuated chips — preventing jamming in deep or interrupted cuts.
Q4: What are typical cutting speed and feed recommendations?
A:
- Steel: 60–120 m/min (200–400 SFM)
- Cast Iron: 80–160 m/min (260–525 SFM)
- Feed per rev: 0.002–0.006 in/rev (depending on setup and diameter)
- Always adjust parameters based on rigidity, coolant, and machine type.
Q5: Does it require coolant?
A: External coolant is recommended for extended life, but the drill can also run dry in short-hole operations due to its TiAlN coating and heat resistance.
Q6: Can it be used on CNC machines?
A: Absolutely. It performs well on CNC vertical machining centers, drill/tap centers, and manual machines requiring tight hole tolerances.
Q7: Is it suitable for reaming or finishing operations?
A: It produces a fine surface finish (Ra ≈ 1.6–3.2 µm), but for ultra-tight tolerance holes, follow up with a reamer.
Q8: How should this drill be stored and maintained?
A: Keep in its protective case, avoid touching the cutting edges, and clean with compressed air — do not use abrasive cleaners that can damage the TiAlN coating.
Q9: Are regrinding or recoating options available?
A: Yes. The Dream Drill can be re-sharpened and re-coated by authorized YG-1 service centers without losing original geometry.
Q10: Is it interchangeable with HSS drills?
A: Functionally yes, but performance is far superior. Carbide with TiAlN runs at 2–3× the speed of conventional HSS or cobalt drills, yielding faster cycles and longer life.
