5D Stainless-Steel Drilling Guidance

  • Coolant Flow: Verify both internal coolant holes are open and maintain reliable coolant delivery throughout the drilling cycle.
  • Rigid Toolholding: Control runout and minimize unnecessary tool overhang to support stable 5×D drilling.
  • Stable Feed: Avoid rubbing or dwell conditions that can accelerate stainless-steel work hardening.
  • Blind-Hole Depth: Allow additional space for the drill point and chip accumulation below the required cylindrical depth.

Recommended Starting Cutting Parameters

Starting values should be selected according to the stainless-steel grade, drill diameter, hole depth, coating, coolant pressure and machine rigidity.

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 Stainless Steel. Final suitability should be confirmed from the exact workpiece grade, hole type, diameter, depth and machining conditions.

Why use a 5D through-coolant drill for stainless steel?

The 5D reach provides additional hole depth while internal coolant helps remove chips and manage heat, both of which are important when drilling stainless steel.

What sizes and configurations are available?

The product is offered around the stated 5D configuration. Other diameter, flute-length, overall-length or shank requirements can be reviewed according to the confirmed specification.

How is coolant delivered on this drill?

This product uses internal through-coolant channels to deliver coolant closer to the cutting zone and support chip evacuation. Coolant pressure and machine capability should be matched to the actual drill size and hole depth.

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 required diameter, hole depth or reach, workpiece material, internal-coolant requirement, 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.
