KENFA Product Family
Boring Sleeves
KENFA Boring Sleeves cover the small-diameter sleeve and boring-accessory routes shown in the catalog. Selection depends on the supported boring tool, sleeve outside diameter, internal bore, overall length, clamping method and machine-side holder. Buyers should send the SHB or TSHB reference, dimensions or a drawing so the fit can be reviewed before quotation.
What should buyers confirm?
Use these fields to narrow the catalog route before KENFA reviews the final model and quotation.
- Supported boring tool
- Sleeve outside diameter
- Internal bore
- Overall length and clamping method
- SHB or TSHB reference
How should buyers narrow this family?
Use the starting point that matches the information already available, then confirm the missing fields before model matching.
| Starting point | Confirm | Why it matters |
|---|---|---|
| Adapt an existing boring tool | Tool shank, sleeve inside and outside diameters, holder bore, engagement length and clamping method | The tool, sleeve and machine-side holder form a three-part fit that must be checked together. |
| Control reach and overhang | Bore entry, machining depth, bar length, sleeve projection, holder position and rigidity concern | A sleeve may fit dimensionally while still leaving an unsupported or obstructed boring setup. |
| Replace an SHB or TSHB sleeve | Complete reference, measured dimensions, supported bar and holder codes and clear photos | The current sleeve reference and interfaces provide the safest route to an exact catalog review. |
Which matching errors should buyers avoid?
These checks keep a family-level inquiry from becoming an unsupported model or compatibility claim.
- Keep sleeve inside diameter, outside diameter and overall length as separate controlled dimensions.
- Confirm the usable clamping length, slot or set-screw position and required projection in the installed assembly.
- Do not infer fit tolerance, material or supported bar compatibility from the model-table image alone.
Buyer questions
Which dimensions are required for a boring sleeve RFQ?
Provide the sleeve inside diameter, outside diameter, overall and clamping lengths, supported bar shank and holder bore.
Can one sleeve adapt any boring bar with the same shank size?
No. Length, clamping position, holder bore, projection and the exact bar and sleeve references also require review.
Why are both the bar and holder codes useful?
They define the two interfaces on either side of the sleeve and help identify where a dimensional mismatch may occur.
