180° Solid Carbide Flat-Bottom Drill | External Coolant

180° Solid Carbide Flat-Bottom Drill

Flat-bottom carbide drill for CNC hole making where a flatter hole bottom or drilling on selected non-flat surfaces is required. This product uses external coolant and is offered in many diameter and length combinations.

How to Select

• Choose the required drill diameter.
• Confirm flute/cutting length against hole depth.
• Check shank diameter and overall length for toolholding and access.
• Review the original cutting guidance below for inclined surfaces, depth and hardness limits.

Typical Applications

• Flat-bottom blind holes
• Counterboring and guide-hole work
• Selected inclined- and curved-surface drilling
• Cross-hole and hole-preparation applications described below

180° Solid Carbide Flat-Bottom Drill

Solid-carbide flat-bottom drill for precision hole making on flat, inclined and curved surfaces. The 180° cutting edge is designed to produce a flatter hole bottom and can help reduce burr formation compared with conventional drill geometry.

Applications

• Inclined-surface and curved-surface drilling
• Counterboring and guide holes
• Cross holes and blind-hole preparation
• Correction of hole deviation in selected applications

Cutting Guidance

• Recommended hole depth: about 2×D under suitable conditions.
• For inclined surfaces, reduce feed as inclination increases.
• Use as a drilling tool only; cross-feed and helical milling are not recommended.
• Recommended workpiece hardness: below approximately HRC45.

This product uses external coolant. Please select the drill diameter, flute length, shank diameter and overall length required for your machining setup.

FAQ

Is this an end mill?
No. The original product guidance identifies it as a drilling tool and does not recommend cross-feed or helical milling.

What coolant type does this version use?
This listing is the external-coolant version.
