Deep-Hole Drilling Guidance
- Pilot Entry: Confirm whether a pilot hole or guided entry is required for the selected drill series.
- Stable Feed: Use a stable and perpendicular entry condition before increasing to the recommended cutting speed.
- Coolant & Evacuation: Maintain continuous coolant delivery and verify chip evacuation throughout the drilling cycle.
- Parameter Verification: Confirm series-specific entry, coolant, and cutting data before machining holes deeper than 8×D.

Product FAQs
Product-specific information about applications, available configurations, customization and machining requirements for this carbide drill.
What materials and applications is this drill designed for?
This product is positioned for steel, stainless steel, and non-ferrous materials. Final suitability should be confirmed from the exact workpiece grade, hole type, diameter, depth, and machining conditions.What does the 8D configuration mean for this drill?
The 8D designation identifies a deep-hole configuration with an intended drilling depth of approximately eight times the drill diameter. The exact usable depth should follow the confirmed specification.What sizes and configurations are available?
The product is offered around the stated 8D configuration. Other diameter, flute-length, overall-length, or shank requirements can be reviewed according to the confirmed specification.What should be considered for chip evacuation?
As reach or hole depth increases, chip control becomes critical. External coolant, air, or mist can be used where suitable, while an internal-coolant version can be reviewed when the application requires stronger chip evacuation.Can the drill geometry or coating be customized?
Yes. Point geometry, flute configuration, edge preparation, and coating can be reviewed according to the application, provided the final specification is technically suitable.What information is required for a quotation?
Please provide the required diameter, hole depth or reach, workpiece material, 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 testing and performance evaluation before committing to volume purchasing.Can mixed sizes be ordered together?
Yes. Standard and custom sizes can be combined in one order when the production and coating requirements are compatible. Mixed-size purchasing is useful for distributors and batch inventory planning.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 and packaging requirements.What is the typical production lead time?
Standard stock items normally have a shorter lead time, while custom tools and special OEM orders require additional production time. The exact schedule is confirmed according to specification, quantity, coating, and current production capacity.Downloads & Technical Resources
