180° Flat-Bottom Drill Overview
This 180° flat-bottom solid carbide drill is designed for counterboring, flat-bottom blind holes, spot-facing and selected entries on inclined or curved surfaces. Its flat cutting geometry supports a controlled hole-bottom profile where a conventional pointed drill is not suitable. Standard and custom configurations can be reviewed for diameter, flute length, overall length, shank, coating, laser marking and packaging according to application and OEM requirements.

Key Configuration
180° Flat Cutting Geometry
The flat-bottom point form is intended for applications requiring a controlled flat hole bottom rather than a conventional conical drill point.
Solid Carbide Construction
The carbide body provides rigidity for counterboring, spot-facing and selected non-flat entry conditions under suitable machining setups.
Customizable Configuration
Diameter, flute length, overall length, shank, coating and packaging can be reviewed according to the required hole geometry and order specification.

Tool Nomenclature & Dimensions
Standard dimensional parameters and technical nomenclature for 180° flat-bottom solid carbide drills. Final geometry, coating and dimensional tolerances are confirmed according to the workpiece material and hole requirements.
Standard Size Matrix
Reference standard sizes for this flat-bottom drill series. Non-standard diameters and length combinations can be reviewed according to drawings or application requirements.
Flat-Bottom Drilling Guidance
- Hole Diameter: Confirm the required finished-hole diameter and diameter tolerance before selecting the tool.
- Entry Condition: Confirm whether the tool enters a flat, inclined, curved or interrupted surface.
- Tool Reach: Use the shortest practical cutting length that can reach the required flat-bottom depth while maintaining rigidity.
- Material & Coolant: Match carbide grade, coating and coolant method to the workpiece grade, hardness and machine setup.
Recommended Starting Cutting Parameters
The following values are general starting references for stable CNC setups. Final cutting conditions should be adjusted according to tool diameter, overhang, workpiece hardness, machine rigidity and coolant supply.

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 selected non-ferrous materials. Final suitability should be confirmed from the exact workpiece grade, hole type, diameter, depth and machining conditions.
What is a 180° flat-bottom drill used for?
The 180° cutting geometry is suited to flat-bottom holes, counterboring and selected inclined-surface entries where a conventional drill point would not provide the required bottom profile.
What sizes and configurations are available?
Standard and custom sizes can be reviewed according to the product series. Diameter, flute length, overall length and shank dimensions should be confirmed before ordering.
What coolant method is suitable?
External coolant, air or mist can be selected according to the workpiece material, hole depth and machine setup. The final method should support stable chip evacuation and temperature control.
Can the coating be selected for the application?
Yes. The final coating should be confirmed according to the workpiece material, hardness, hole condition and expected cutting environment.
What information is required for a quotation?
Please provide the required diameter, hole depth or reach, workpiece material, coating 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.
