Designed for stable extra-deep-hole drilling in cast iron materials, this 15xD carbide drill combines imported MG grade 0.8 μm carbide, ALTISIXN wear-resistant coating, optimized point geometry, reinforced extra-deep-hole flute structure, and reliable chip removal support to improve abrasive wear resistance, powdery chip discharge, edge protection, hole straightness, and process stability in long-depth cast iron machining.
The 15xD carbide drill for cast iron is designed for extra-deep-hole machining applications where abrasive wear resistance, powdery chip discharge, hole straightness, flute rigidity, and process stability are critical. Compared with 12xD drilling, 15xD cast iron drilling has a longer chip discharge distance and higher requirements for guide stability, spindle runout control, and chip removal support.
Cast iron materials such as grey cast iron, ductile iron, nodular cast iron, and compacted graphite iron are abrasive during drilling. Powdery chips, graphite particles, hard casting skin, and uneven cast surfaces may accelerate cutting edge wear or cause micro-chipping. In 15xD extra-deep-hole drilling, chips travel a much longer path, so poor chip discharge can increase friction inside the hole, affect hole straightness, and shorten tool life.
This 15xD carbide drill is manufactured from imported MG grade 0.8 μm tungsten carbide rods with 10% cobalt content, supporting stable tool strength and wear resistance. Combined with ALTISIXN wear-resistant coating, optimized point geometry, reinforced extra-deep-hole flute structure, controlled edge preparation, and German Walter precision grinding, it helps improve edge protection, chip discharge, and reliable hole consistency in extra-deep cast iron drilling applications.

Key Features
Made from imported MG grade 0.8 μm tungsten carbide with 10% cobalt content.
The fine carbide grain structure helps support tool rigidity, edge strength, and stable wear resistance in extra-deep cast iron hole machining.
ALTISIXN coating helps protect the cutting edge against abrasive wear in cast iron drilling.
It supports stable cutting performance, reduces premature edge wear, and helps improve tool life in 15xD extra-deep-hole applications.
Optimized drill point geometry supports stable entry and accurate hole positioning.
A stable drill point helps reduce drill walking, improves starting accuracy, and supports better hole straightness during extra-deep drilling.
Reinforced flute geometry improves powdery chip discharge and tool rigidity in 15xD cast iron drilling.
The variable core design and back taper help reduce friction inside the hole, protect the cutting edge, and maintain stable hole quality over longer drilling depths.
This 15xD carbide drill for cast iron is suitable for extra-deep-hole machining in CNC machining centers and production drilling applications. It is especially useful for cast iron components where abrasive wear resistance, powdery chip discharge, edge protection, hole straightness, and batch drilling stability are important.

Edge Passivation Control
Our carbide drills are ground on German WALTER 5-axis grinding machines for sharp cutting edges, stable accuracy, and smooth drilling performance.
We use WALTER HELICHECK PLUS for contour inspection, keeping profile and radius control within 3 μm for reliable geometric precision.
Each carbide drill is inspected at 300x magnification to check edge quality and avoid chipping or saw-tooth defects before shipment.
Manual drill point honing and automatic rubber-bonded diamond abrasive polishing help improve tool life and control edge consistency within ±0.003 mm.
Common Questions
15xD means the drill is designed for hole depths up to 15 times the drill diameter. It is used for extra-deep-hole machining where chip discharge, tool rigidity, edge protection, and hole straightness are more demanding.
Yes. This 15xD carbide drill is suitable for grey cast iron, ductile iron, nodular cast iron, compacted graphite iron, and other cast iron materials under suitable machining conditions.
This drill uses ALTISIXN wear-resistant coating, which helps improve abrasive wear resistance, edge protection, and tool life in cast iron extra-deep-hole drilling applications.
Cast iron is abrasive and produces powdery chips. In 15xD drilling, chips travel a longer distance, and abrasive particles may increase tool wear or friction inside the hole. Stable chip discharge and edge protection are critical for maintaining hole quality and tool life.
A 12xD drill is used for deep-hole drilling, while a 15xD drill is designed for longer and more demanding holes. 15xD drilling requires better chip discharge, stronger flute rigidity, careful runout control, and more stable machine conditions.
Internal coolant or air-blast support is recommended according to the cast iron grade, machine condition, and chip removal requirement. For 15xD holes, stable chip discharge is important to maintain hole quality and tool life.
Yes. We support customization based on drawings, cast iron grade, diameter, hole depth, chip removal method, ALTISIXN coating requirement, shank size, and drilling application.
Yes. Regrinding service is available depending on drill size, wear condition, and application requirements.
