Custom-Diameter Solid Carbide Twist Drill for Aluminum Overview
This custom-diameter solid carbide twist drill is designed for aluminum-alloy holes that cannot be covered efficiently by standard drill sizes. Cutting diameter, tolerance, drilling depth, shank, point geometry, flute profile and surface treatment can be matched to the customer drawing, workpiece alloy and CNC process. Fine-grain solid carbide and a two-flute configuration provide a rigid base for precision hole machining, while polished flute surfaces or optional DLC coating can be selected to reduce adhesion and support cleaner chip flow in aluminum applications.

Key Configuration
Custom Diameter & Tolerance
Metric, inch, intermediate and drawing-specific diameters can be produced, with manufacturing tolerance selected for the required hole result.
Aluminum-Specific Geometry
Sharp point geometry, thinning, edge preparation and application-specific flute profiles can be selected according to the exact alloy and chip behavior.
Polished or DLC Surface
Polished uncoated surfaces or optional low-friction DLC coating can be matched to adhesion tendency, production volume and alloy condition.
Key Product Advantages
Drawing-Based Diameter Control
The cutting diameter and tool tolerance can be matched directly to non-standard hole requirements rather than limited to catalogue sizes.
Reduced Aluminum Adhesion
Sharp geometry, polished chip surfaces and optional DLC help address the adhesion and chip-sticking behavior common in many aluminum alloys.
Custom Length & Shank
Flute length, overall length and cylindrical shank diameter can be matched to the holder interface, machine clearance and required reach.
OEM Repeat-Supply Configuration
Approved geometry, polishing, DLC coating, tolerance and laser marking can be reproduced for repeat project and OEM orders.
Workpiece Material Compatibility

Product & Cutting-Edge Details
Tool Nomenclature & Configurable Specifications
This custom-diameter solid carbide twist drill is configured around the required hole size and aluminum-alloy application rather than a fixed catalogue diameter series. Cutting diameter, tolerance, flute length, overall length, shank diameter, point geometry, surface treatment and coolant configuration should be confirmed together from the drawing and machining conditions.
Custom Dimension & Configuration Scope
This product is produced from an approved drawing or application requirement rather than a fixed row-by-row size matrix.

Aluminum Drilling Guidance
- Control Diameter & Runout: Match tool tolerance, holder accuracy and machine condition to the required hole result.
- Maintain Continuous Feed: Avoid rubbing and dwell, which can increase aluminum adhesion and hole variation.
- Provide Chip Space: Select flute length and flute profile according to actual hole depth and expected chip form.
- Use Suitable Lubrication: Direct coolant or lubricant toward the cutting zone and flute entrance.
Material-Specific Design Guidance
The original product page provides alloy-specific design directions rather than fixed numerical cutting parameters.
| MATERIAL | MAIN CHALLENGE | CUSTOM DESIGN DIRECTION |
|---|---|---|
| 6061 / 6082 | Long chips and adhesion | Sharp geometry, polished flutes and stable lubrication |
| 7075 | Higher strength and load | Rigid geometry, low runout and controlled edge preparation |
| Pure Aluminum | High adhesion tendency | Maximum sharpness, polished chip surfaces and optional DLC |
| Selected Cast Aluminum | Wear varies with silicon content | Confirm the alloy before selecting carbide, coating and edge design |

Product FAQs
Product-specific information about custom-diameter carbide drilling, DLC coating, aluminum-alloy machining, chip evacuation and application-specific tool configuration.
What does “custom diameter” mean for this carbide drill?
Custom diameter means the cutting diameter can be produced according to a non-standard metric, inch or intermediate hole size rather than being limited to standard catalogue dimensions. The required hole diameter, tolerance and downstream machining process should be confirmed before production.
Why is DLC coating used for aluminum-alloy drilling?
DLC is a low-friction coating option commonly considered for aluminum and other non-ferrous applications where material adhesion and built-up edge can affect chip flow and hole quality. Final coating selection should still be matched to the exact aluminum grade, drilling depth and production conditions.
What aluminum alloys can this drill be used for?
The drill can be configured for different aluminum-alloy applications according to the exact material grade and machining requirement. Please provide the alloy designation, material condition, hole depth and required tolerance so that the cutting geometry and DLC configuration can be reviewed correctly.
What machining conditions are important when drilling aluminum?
Low runout, rigid clamping, stable feed and reliable chip evacuation are important. Air, mist or coolant delivery should be selected according to the aluminum grade, hole depth and machine setup. Avoid conditions that allow chips to accumulate or material to adhere to the cutting edge.
Can the flute length, shank and overall length also be customized?
Yes. In addition to the cutting diameter, flute length, shank diameter, overall length, point geometry, edge preparation and other dimensional details can be reviewed according to the hole depth, holder interface and machine clearance. A drawing is recommended for non-standard configurations.
What information is required for a quotation?
Please provide the required cutting diameter, hole tolerance, hole depth, blind-hole or through-hole requirement, aluminum-alloy grade, flute length, shank diameter, overall length, coolant condition, machine type and required quantity. A drawing or existing tool sample is recommended for special-diameter projects.
Ordering & OEM FAQs
General information for trial orders, mixed sizes, OEM marking and repeat distributor supply.
Do you accept small trial orders?
Yes. Small trial quantities can be reviewed for dimensional verification, hole-quality testing, chip-evacuation evaluation and tool-life comparison before larger repeat orders.
Can different custom diameters be ordered together?
Yes. Multiple cutting diameters and length configurations can normally be combined in one order when the carbide, DLC coating and production requirements are compatible.
Is OEM laser marking available?
Yes. Logo, item code, drill size and batch identification can be reviewed for laser marking where the available shank area permits. Custom labels and private-brand packaging are also available for OEM programs.
What is the typical production lead time?
Lead time depends on the custom diameter, tolerance, flute length, DLC coating, special geometry and order quantity. Final production scheduling is confirmed after the drawing or tool specification is approved.
