AMG’s TiAlN-coated carbide through-coolant drill is engineered for
high-efficiency and high-precision deep hole machining in engine
manufacturing. Use ultra-fine grain carbide substrates with
advanced TiAlN PVD coatings, these drills have exceptional wear
resistance, heat resistance, and stability during high-speed and
long-depth drilling operations on aluminum alloy, cast iron, and
steel engine blocks.
Applications:
Engine Block Machining: Drilling oil holes, water cooling channels,
and head bolt holes in automotive and motorcycle engine blocks.
Automotive Manufacturing: Suitable for aluminum alloy, cast iron,
and CGI engine components requiring high precision and clean bore
finishes.
Powertrain Component Manufacturing: Used for crankcases, cylinder
heads, and transmission housings.

Working Principle
The AMG TiAlN-coated carbide through-coolant drill uses high-speed
rotation and optimized chip evacuation while coolant passes
internally through the drill to the cutting edge. This ensures
effective heat dissipation and lubrication, prevents thermal
deformation, and remain consistent hole quality during deep hole
drilling in engine blocks. The TiAlN coating reduces friction and
oxidation at high temperatures, while the precision-ground geometry
enhances centering and drilling stability.
Advantages:
✅ Extended Tool Life: TiAlN coating offers superior heat and wear
resistance during high-speed drilling.
✅ Efficient Chip Evacuation: Through-coolant design prevents chip
packing and breakage in deep hole drilling.
✅ High Stability: AMG’s precision manufacturing ensures excellent
concentricity for high-accuracy holes.
✅ Smooth Bore Finish: Offer low roughness and clean hole surfaces,
reducing the need for additional honing.
FAQ
1. What materials can this drill handle?
It is suitable for aluminum alloys, cast iron, compacted graphite
iron (CGI), and steel engine blocks.
2.Why is the TiAlN coating beneficial?
TiAlN provides excellent thermal stability and reduces friction,
extending tool life during high-speed and dry or MQL machining.
3. What is the recommended cutting speed?
Typical speeds are 60-150 m/min for cast iron and 150-300 m/min for
aluminum alloys, depending on the coolant system and machine
rigidity.
