Woodruff Keyseat Cutter Specifications
The table below lists five representative models from the metric HSS Woodruff keyseat cutter series. Each model has a specific combination of cutter diameter, cutting width, shank diameter, neck diameter, overall length, and tooth count. Each model follows its own dimensional configuration, so do not mix dimensions from different models.
| Nominal Size | Cutter Dia. (d) | Width (b) | Shank Dia. (d1) | Neck Dia. (d2) | OAL (L) | Teeth (Z) |
|---|---|---|---|---|---|---|
| 3 × 13 | 13.8 | 3 | 10 | 4.6 | 60 | 6 |
| 4 × 19 | 20.1 | 4 | 10 | 6 | 60 | 8 |
| 6 × 25 | 26.5 | 6 | 12 | 8 | 60 | 8 |
| 8 × 32 | 33.9 | 8 | 12 | 10 | 65 | 10 |
| 10 × 45 | 47.7 | 10 | 15 | 14 | 70 | 10 |
All dimensions are in millimeters (mm).
Applications & Size Selection
Woodruff key cutters mill keyseats in shafts for mechanical connections. The curved portion of a Woodruff key fits into the shaft keyseat, while the exposed portion engages a mating keyway in a gear, pulley, or other hub component.
The required keyseat geometry determines the cutter selection. Check the actual cutter diameter and cutting width against the shaft or keyseat drawing. Neck diameter affects clearance around the cutting head, while the shank diameter must suit the toolholder.
Before confirming the cutter specification, also check the overall length, available machining space, and workpiece material.
For T-shaped undercuts rather than shaft keyseats, see our T Slot Cutter.
Custom Sizes & Drawing Review
For Woodruff cutters with dimensions outside the listed reference series, customers can submit an existing cutter model, dimensioned tool drawing, or shaft/keyseat drawing.
For non-standard cutter configurations, we review the specified dimensions, geometry, and application requirements with our production team before confirming manufacturing feasibility and quotation.
Frequently Asked Questions
Can I request a quotation using an existing cutter model?
Yes. You can provide the manufacturer’s model number or an existing cutter reference. Please include any available dimensions so we can check the required tool specifications.
Can I request Woodruff cutters in inch sizes?
The reference HSS series uses metric dimensions. You can submit an inch-based drawing or specification for review. We will review manufacturing feasibility for inch-size requests separately.
What if I only know the Woodruff key size?
You can provide the Woodruff key designation or the required shaft keyseat dimensions. We may need additional cutter dimensions to confirm the correct tool before quotation.
