Jobber-Length Carbide Twist Drill
This 2-flute jobber-length solid carbide twist drill is designed for routine CNC drilling where a practical balance of reach, rigidity and chip evacuation is required. Compared with stub drills, the jobber-length configuration provides additional reach while remaining more rigid than long-series tools. Two spiral flutes support chip removal in blind-hole and through-hole machining, while the fine-grain carbide body helps maintain stable hole quality in repeat production. The reference series covers Ø0.5–13.0 mm, with flute length, shank diameter, overall length, point geometry and coating selected according to the required diameter and application.

Product & Cutting-Edge Details
Tool Nomenclature & Dimensions
This jobber-length solid carbide twist drill series is intended for general CNC drilling where balanced reach and rigidity are required. Reference dimensions cover Ø0.5–13.0 mm cutting diameter, 5–77 mm flute length, Ø4–13 mm shank diameter and 50–124 mm overall length. Final L1, d and L depend on the selected cutting diameter and tool configuration.
Reference Size Range
The original product page provides the following dimensional ranges rather than a fixed row-by-row size matrix.
| DIMENSION | REFERENCE RANGE | REMARKS |
|---|---|---|
| Cutting Diameter D | 0.5–13.0 mm | Standard and custom diameters |
| Flute Length L1 | 5–77 mm | Varies with cutting diameter |
| Shank Diameter d | 4–13 mm | Reinforced shank available |
| Overall Length L | 50–124 mm | Jobber-length configuration |
| Custom Dimensions | On Request | Confirm D × L1 × d × L |
Jobber-Length CNC Drilling Guidance
- Use a Precision Holder: Keep spindle and holder runout low to support stable hole position and cutting-edge loading.
- Control Tool Overhang: Keep overhang as short as practical while maintaining the reach required for the hole.
- Maintain Chip Removal: Use reliable external coolant or air blast according to the workpiece and hole condition.
- Match Cutting Data: Speed and feed should be selected according to material, coating, cutting diameter and hole depth.
- Choose the Correct Length Series: Use a stub drill when maximum rigidity is required and a long-series drill when additional reach exceeds the jobber-length range.
Recommended Starting Cutting Parameters
The original product page does not provide a fixed speeds-and-feeds table. Starting parameters should therefore be selected according to the exact steel grade, hardness, drill diameter, coating, hole depth, holder runout and coolant condition.

Product FAQs
Product-specific information about jobber-length carbide drilling, 2-flute geometry, steel machining, chip evacuation, toolholding and machining setup.
What is a jobber-length solid carbide twist drill used for?
A jobber-length solid carbide twist drill is intended for general CNC hole machining where more reach is required than a stub-length drill but an extra-long tool is unnecessary. It provides a practical balance between drilling reach, tool rigidity and chip evacuation for routine steel machining.
What types of steel can this drill be used for?
The drill can be configured for carbon steel, alloy steel and other confirmed steel grades. Final carbide grade, point geometry, edge preparation and coating should be selected according to the exact material grade, hardness, heat treatment and required hole depth.
Why does this drill use two spiral flutes?
The two-flute geometry provides two cutting edges and dedicated chip channels for continuous chip removal during drilling. Stable chip evacuation is especially important in blind holes and deeper jobber-length applications where chips must travel farther before leaving the hole.
What machining conditions are important for accurate steel drilling?
Use a rigid CNC machine, accurate toolholder, low spindle runout, secure workpiece clamping and the shortest practical tool overhang. Stable feed, controlled entry and reliable coolant delivery also help maintain hole position, diameter and cutting-edge condition.
Can the diameter, flute length and coating be customized?
Yes. Cutting diameter, flute length, overall length, shank diameter, point geometry, edge preparation and coating can be reviewed according to the steel grade, hole depth, tolerance and CNC setup. Non-standard dimensions can also be evaluated from a drawing or existing tool sample.
What information is required for a quotation?
Please provide the cutting diameter, hole depth, blind-hole or through-hole requirement, steel grade, hardness, flute length, shank diameter, overall length, required tolerance, coolant condition, machine type and quantity. A drawing is recommended for non-standard dimensions or special hole requirements.
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 hole-quality testing, dimensional verification, chip-evacuation evaluation and tool-life comparison before larger repeat orders.
Can mixed drill sizes be ordered together?
Yes. Different cutting diameters and length configurations can normally be combined in one order when the carbide grade, geometry, coating and production requirements are compatible.
Is OEM laser marking available?
Yes. Logo, item code, tool 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 cutting diameter, flute length, coating, custom geometry and order quantity. Final production scheduling is confirmed after the tool specification and application requirements are approved.
