Designed for stable extra-deep-hole drilling in aluminum and non-ferrous materials, this 15xD carbide drill combines imported MG grade 0.8 μm carbide, sharp cutting edge preparation, uncoated or DLC coating options, optimized point geometry, reinforced extra-deep-hole flute structure, and internal coolant support to reduce chip adhesion, improve long-distance chip evacuation, and maintain clean hole wall quality in demanding aluminum deep-hole machining.
The 15xD carbide drill for aluminum is designed for extra-deep-hole machining applications where chip evacuation, low cutting resistance, hole wall finish, tool rigidity, and process stability are critical. Compared with 12xD drilling, 15xD aluminum drilling has a longer chip evacuation path and places higher demands on flute smoothness, coolant delivery, spindle runout control, pilot hole quality, and machine stability.
Aluminum and aluminum alloys are soft and adhesive during drilling. In 15xD extra-deep-hole machining, long aluminum chips may stick to the cutting edge, accumulate inside the flute, scratch the hole wall, or increase cutting resistance. If chip adhesion, chip evacuation, and coolant support are not controlled, the drill may face built-up edge, chip clogging, poor surface finish, hole deviation, or premature tool failure.
This 15xD carbide drill is manufactured from imported MG grade 0.8 μm tungsten carbide rods with 10% cobalt content, supporting high-speed cutting and stable tool strength. Uncoated options provide sharp cutting performance and low cutting resistance for general aluminum drilling, while DLC-coated options offer a low-friction surface to reduce built-up edge, chip sticking, and hole wall scratches in aluminum and non-ferrous material machining.

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 sharpness, and stable cutting performance in extra-deep aluminum hole machining.
Uncoated drills provide sharp cutting performance and low cutting resistance for general aluminum extra-deep-hole drilling.
DLC coating provides a low-friction surface that helps reduce aluminum adhesion, built-up edge, chip sticking, and hole wall scratches.
Optimized drill point geometry supports stable entry and accurate hole positioning.
A sharp and stable drill point helps reduce cutting resistance, improve starting accuracy, and support better hole straightness before long-depth drilling.
Reinforced flute geometry supports long-chip evacuation and tool rigidity in 15xD aluminum drilling.
The variable core design and back taper help reduce friction inside the hole, improve chip flow, lower chip clogging risk, and maintain cleaner hole wall quality over longer drilling depths.
This 15xD carbide drill for aluminum is suitable for extra-deep-hole machining in CNC machining centers and production drilling applications. It is especially useful for aluminum components where long-chip evacuation, anti-adhesion performance, internal coolant delivery, clean hole walls, hole straightness, and batch drilling stability are important.

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 evacuation, coolant delivery, tool rigidity, hole straightness, and process stability are more demanding.
Yes. This 15xD carbide drill is suitable for aluminum, aluminum alloys, cast aluminum, copper alloys, brass, and other non-ferrous materials under suitable machining conditions.
Uncoated drills are suitable for general aluminum drilling where sharp cutting performance and low cutting resistance are required. DLC-coated drills are recommended when better anti-adhesion performance, lower friction, smoother chip evacuation, and cleaner hole walls are needed.
Aluminum is soft and adhesive. In 15xD deep-hole drilling, long chips must travel a much longer distance before leaving the hole. If chips stick inside the flute, they may cause built-up edge, chip clogging, hole wall scratches, or unstable hole accuracy.
A 12xD drill is used for deep-hole drilling, while a 15xD drill is designed for longer and more demanding holes. 15xD drilling requires smoother chip flow, stronger coolant support, better flute rigidity, more careful runout control, and more stable machine conditions.
DLC coating provides a low-friction surface that helps reduce aluminum adhesion, chip sticking, and built-up edge. It is especially suitable for aluminum and other non-ferrous materials where clean hole walls and smooth chip evacuation are required.
Yes. Internal coolant is recommended for 15xD aluminum drilling because it helps support long-chip evacuation, reduce chip adhesion, lower cutting temperature, and maintain stable hole wall quality.
Yes. We support customization based on drawings, aluminum grade, diameter, hole depth, coolant method, uncoated or DLC coating requirement, shank size, and drilling application.
