AlTiN-Coated Carbide Twist Drill
This precision-ground 2-flute solid carbide twist drill is designed for stable CNC drilling in alloy steel and selected pre-hardened steel. Its AlTiN coating helps protect the cutting edges from heat and abrasive wear, while the two-flute geometry provides chip space and supports consistent hole production under rigid machining conditions. Standard 3×D and 5×D configurations are available, while diameter, length, point geometry, coolant channels, tolerance, marking and packaging can be reviewed for custom or OEM requirements.
Key Configuration
AlTiN-Coated Cutting Edges
The coating supports heat and abrasive-wear resistance during alloy-steel drilling.
Two-Flute Chip Space
Two spiral flutes balance carbide strength with space for chip formation and evacuation.
3×D and 5×D Series
Standard depth configurations cover common blind-hole and through-hole requirements.
Key Product Advantages
Workpiece Material Compatibility
Actual machinability depends on alloy content, heat treatment, hardness, drilling depth and machine condition.

Alloy-Steel Drilling Guidance
- Rigid Clamping: Use a rigid holder and control cutting-edge runout.
- Hardness Adjustment: Reduce cutting speed as workpiece hardness and drilling depth increase.
- Stable Feed: Maintain continuous feed to avoid rubbing and localized work hardening.
- Coolant & Chips: Provide consistent coolant flow and verify chip evacuation.

Product FAQs
Product-specific information about alloy steel applications, 2-flute cutting geometry, AlTiN coating, coolant selection and available configurations for this solid carbide twist drill.
Which materials is this drill designed for?
This drill is designed primarily for ISO P materials, including carbon steel, low-alloy steel, medium-alloy steel and selected tool steels. Final suitability should be confirmed according to the exact material grade, hardness, hole depth and machining conditions.
What are the benefits of the AlTiN coating?
The AlTiN coating provides heat resistance and wear protection during alloy steel drilling. It helps protect the cutting edges under elevated cutting temperatures and supports more consistent tool life in suitable CNC machining conditions.
Why does this drill use a 2-flute geometry?
The 2-flute geometry provides a practical balance between cutting-edge strength, tool rigidity and chip space. Its spiral flutes support controlled chip formation and evacuation during blind-hole and through-hole drilling in alloy steel.
What workpiece hardness can this drill machine?
The suitable hardness range depends on the alloy steel grade, heat-treatment condition, drill diameter, hole depth, coating and machine rigidity. Please provide the actual workpiece hardness so the carbide grade, edge preparation and cutting parameters can be confirmed.
Is this drill suitable for blind holes and through holes?
Yes. It can be configured for both blind-hole and through-hole drilling. The required flute length, usable drilling depth, point allowance and chip-evacuation space should be confirmed before ordering.
What coolant method is recommended?
External coolant is suitable for many short-hole applications, while through coolant is recommended for deeper holes or conditions requiring improved chip evacuation and temperature control. The final method should be selected according to the drilling depth, diameter and machine setup.
What information is required for a quotation?
Please provide the required diameter, hole depth, alloy steel grade, actual hardness, coolant method, tolerance and estimated quantity. A drawing is recommended for stepped, long-reach or other non-standard drill requirements.
Ordering & OEM FAQs
General information for trial orders, mixed-size purchasing, private labeling and production scheduling.
Do you accept small trial orders?
Yes. Small sample or trial orders are welcomed for evaluating hole quality, chip evacuation, cutting stability and tool life before committing to volume purchasing.
Can mixed sizes be ordered together?
Yes. Standard and custom sizes can be combined in one order when the geometry, carbide grade and coating requirements are compatible. Mixed-size purchasing is suitable for distributors, wholesalers and batch inventory planning.
Can the drill dimensions and geometry be customized?
Yes. The cutting diameter, flute length, overall length, shank diameter, point geometry, flute profile, edge preparation, coolant configuration and dimensional tolerance can be reviewed according to the application or customer drawing.
Is OEM laser marking available?
Yes. Custom shank laser marking such as logo, model number, specifications or batch identification can be reviewed together with OEM labels, individual tool protection and branded packaging requirements.
What is the typical production lead time?
Standard stock items normally have a shorter lead time, while custom dimensions, special coolant configurations and OEM orders require additional production time. The exact schedule is confirmed according to specification, quantity, coating and current production capacity.
