Ball Nose End Mills for Titanium
Select a ball nose end mill for titanium by the contour, cutting diameter and access your job requires. The KB series has a rounded cutting end and two flutes, with individual model dimensions for building a repeatable tooling assortment.
- Rounded end profile for contour and three-dimensional milling
- Two-flute KB series with model-level dimensions
- Compare diameter, ball radius, flute length and shank size
Select a Ball Nose End Mill for Titanium Contours
A ball nose end mill presents a rounded cutting profile to the programmed surface. A square end mill for titanium can also be programmed for some three-dimensional work, but its contact geometry and toolpath requirements differ. For titanium components, start with the surface drawing and the space around the feature, then select the KB model that fits the planned holder and toolpath.
- Match ball radius to the feature and programmed path
- Check flute length and holder clearance for recessed areas
- Keep each diameter and shank combination on its own order line
KB Series and Ordering Dimensions
The catalog lists 23 KB models. The specification table provides the cutting diameter, radius, flute length, overall length, shank diameter and flute count for each model. Use the product drawing alongside the table when comparing tools.
The ball radius describes the rounded tool end; it is not the corner radius of a flat-ended bull-nose cutter. A larger ball can follow a different path and produce a different surface pattern. Check the radius against the part geometry instead of selecting by diameter alone.
Shank options can differ even when cutter diameter matches. Keep the complete model code, radius and holder size together in your quotation request.
Check Access Before Approving a Model
For a curved cavity, consider the contour depth, the opening around the tool and the position of clamps and holders. Compare flute length with the operation, then check overall tool length and holder projection against the setup. Do not treat total length as a guarantee of usable reach.
When the cutting contact is near the tip, the effective cutting diameter can be smaller than the nominal diameter. This changes the local cutting speed at a given spindle speed. For contouring, provide the relevant contact and engagement conditions rather than selecting speed from nominal diameter alone. Use the tool and machine supplier’s guidance for the specific material and operation.
Titanium Application Details for Your RFQ
Send the titanium grade and condition, the contour or feature drawing, and whether the tool is being selected for finishing or another operation. Include the machine, holder and coolant arrangement used by the customer. These details help identify the constraints that may not appear in a simple diameter list.
For distribution orders, group models by the sizes required by the customer and indicate quantities per item. If a tool is intended for a replacement order, provide the current model or drawing dimensions rather than relying on appearance.
Ball Nose, Square End or Corner Radius?
A ball nose tool has a rounded end across the cutting profile. A square-end cutter is used for nominally flat floors and straight shoulders; a corner-radius cutter combines a flat end with rounded outer corners. Compare the required geometry and toolpath before choosing a replacement.
Sample and Repeat-Order Requirements
Identify the ball profile, cutting diameter, shank and lengths that are important to your receiving checks. Share the drawing revision and any sample, identification or packaging requirements with the RFQ. For repeat orders, keep the same model and agreed specification on the purchase record.
For a different feature profile, compare the square end mill for titanium and corner radius end mill for titanium against the same part drawing.

Frequently Asked Questions
What is a ball nose end mill used for in titanium?
It can be selected for curved profiles, contours and three-dimensional features. Suitability depends on the titanium grade, model, feature and machine setup.
What should I check besides cutting diameter?
Compare the ball radius, flute length, overall length and shank diameter against the part and holder requirements.
How many flutes do the listed KB models have?
The catalog identifies the listed KB series as two-flute. Review the individual model row for its other dimensions.
What should I check when replacing another ball nose cutter?
Compare the ball profile and radius, diameter, flute length, overall length and shank against the existing tool drawing. Ask for a trial if the material grade, holder or toolpath differs.
What should I check for titanium contour milling with a KB tool?
Compare the ball radius and toolpath with the feature, then check the selected cutter and holder for access. State the titanium grade and machine setup when requesting a model review.
What information is useful for a wholesale quote?
Provide the KB model and quantity per size, or the diameter, radius, lengths and shank size. Include the titanium grade, feature drawing and any sample or packaging requirements.
