Carbide Twist Drill for HRC50–55 Mold Steel
This coated solid carbide twist drill is designed for stable CNC hole machining in heat-treated mold steels with a measured hardness of HRC50–55. Its rigid carbide body, precision-ground two-flute geometry and wear-resistant coating help manage cutting-edge load, heat and abrasive wear. The standard configuration uses a cylindrical straight shank and external coolant and is intended for rigid machining centers, low-runout clamping, controlled entry and hole depths compatible with the selected flute length.

External Coolant
Key Configuration
1
HRC50–55 Application Window
Geometry, carbide substrate and coating are selected for heat-treated mold steel within the confirmed HRC50–55 range.
2
Coated Two-Flute Geometry
Two spiral flutes provide chip space, while the coated cutting zone helps manage heat and abrasive wear.
3
External-Coolant Configuration
The standard configuration uses directed external coolant and requires reliable coolant access to the flutes.
Key Product Advantages
●
Rigid Solid-Carbide Body
High tool rigidity supports edge stability and helps limit deflection when drilling heat-treated mold steel.
●
Wear-Resistant Coating
A suitable PVD coating protects the cutting zone against heat and abrasive wear during continuous CNC drilling.
●
Two-Flute Chip Space
The two-flute design provides chip space and supports controlled chip evacuation when coolant access is maintained.
●
Precision-Ground Point
Symmetrical cutting lips support controlled entry and stable cutting when holder runout and workpiece clamping are controlled.
Mold Steel & Hardness Guidance
Tool selection should be based on measured workpiece hardness rather than the material-grade name alone. Confirm the heat-treatment condition and local surface hardness before drilling.
| MATERIAL CONDITION | TYPICAL EXAMPLES | SELECTION GUIDANCE |
|---|---|---|
| Heat-Treated Hot-Work Mold Steel | H13, SKD61, 1.2344 | Confirm measured hardness within HRC50–55. |
| Heat-Treated Stainless Mold Steel | S136, 1.2083 | Confirm grade, heat treatment and actual hardness. |
| Selected Cold-Work / Tool Steel | Application-specific grades | Use when measured hardness is within HRC50–55. |
| Outside the Rated Range | Below HRC50 or above HRC55 | Review another geometry, coating or drilling process. |
Applications & Target Scope
- Precision hole machining in heat-treated mold components
- Drilling H13, SKD61 and 1.2344 after hardness confirmation
- Selected stainless mold steels such as S136 and 1.2083
- Blind-hole and through-hole machining within the selected flute length
- Rigid CNC machining with low runout and controlled tool entry
- Standard and custom drill configurations for mold-making applications
Requisitos de la aplicación
• Verify Actual Hardness
Confirm the mold-steel grade, heat-treatment condition and measured hardness before selecting the drill.
• Maintain Low Runout
Use a clean precision holder, rigid workholding and the shortest practical tool overhang.
• Control Tool Entry
Use a flat and stable entry where possible to reduce vibration, edge chipping and hole deviation.
• Maintain Coolant Access
Direct suitable coolant into the flutes and monitor chip evacuation throughout the drilling cycle.
See the tooling-as-a-system guide for holder, spindle, workholding and coolant considerations.

Recomendaciones de mecanizado
- Verify Actual Hardness: Confirm the mold-steel grade, heat treatment and measured workpiece hardness.
- Maintain Low Runout: Use a precision holder, short tool overhang and rigid workholding.
- Control the Entry: Use a flat and stable entry where possible to reduce vibration and edge chipping.
- Maintain Coolant Access: Direct suitable coolant into the flutes and monitor chip evacuation.
- Match the Cycle to Depth: Select pecking and chip-clearing strategy according to diameter, depth and flute length.
- Verify Cutting Data: Match speed and feed to material grade, hardness, diameter, coating and machine rigidity.

Product FAQs
Product-specific information about mold-steel applications, HRC50–55 hardness positioning, coating selection, available configurations and machining requirements for this solid carbide twist drill.
What materials is this carbide drill designed for?
This coated solid carbide twist drill is positioned primarily for pre-hardened mold steel, tool steel and selected alloy-steel grades within the HRC50–55 range. Final suitability should be confirmed according to the exact material grade, actual hardness, hole type, drilling depth and machine conditions.
What does the HRC50–55 designation mean?
HRC50–55 describes the intended workpiece-hardness range for selected stable machining conditions. It is not the hardness of the carbide drill itself or a universal performance guarantee. Workpiece composition, actual hardness, hole depth, tool overhang, runout and machine rigidity must also be considered.
Why is a coated drill recommended for hardened mold steel?
A suitable PVD coating helps manage friction, cutting heat and abrasive wear when drilling hardened mold steel. The final coating should be selected according to the workpiece grade, hardness, coolant method, cutting parameters and required tool-life target.
What setup is recommended when drilling HRC50–55 mold steel?
Use a rigid CNC machine, a clean low-runout holder and the shortest practical tool overhang. Stable coolant delivery and controlled chip evacuation are important, while speed and feed should be matched to the exact steel grade, hardness, drill diameter and hole depth.
What sizes and drill configurations are available?
Standard and custom configurations can be reviewed according to the product series. Cutting diameter, flute length, shank diameter, overall length, drilling depth, point geometry, coating and coolant configuration should be confirmed before ordering.
What information is required for a quotation?
Please provide the required diameter, hole depth or flute length, shank diameter, overall length, workpiece grade and hardness, blind-hole or through-hole condition, coating requirement, coolant method and estimated quantity. A drawing is recommended for custom or non-standard 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 checking hole quality, cutting stability, chip evacuation and tool life in the intended mold-steel grade before volume purchasing.
Can mixed sizes be ordered together?
Yes. Standard and custom sizes can be combined in one order when the carbide grade, coating and production requirements are compatible. Mixed-size purchasing is suitable for distributors and multi-diameter mold-machining requirements.
Is OEM laser marking available?
Yes. Custom shank laser marking such as a logo, model number, tool dimensions, hardness range or batch identification can be reviewed together with OEM labels and packaging requirements.
What is the typical production lead time?
Standard stock items normally have a shorter lead time, while custom dimensions, special coatings and OEM orders require additional production time. The exact schedule is confirmed according to specification, quantity, coating and current production capacity.
