1. Product Overview
The Kyocera 1/16 REAMER 4FL REAMER SGS70004 is a Kyocera solid carbide machine reamer with Ø16 mm cutting diameter and 4-flute geometry, producing H7-class precision holes with Ra 0.4–0.8 µm surface finish directly after drilling. Micro-grain carbide at HRA 92+ holds size across long production runs where HSS reamers drift.
Leave 0.15–0.30 mm stock on diameter for this size — pre-drill at approximately Ø15.75 mm. At Vc 12 m/min on steel, Ø16 mm runs ≈ 238 RPM at 0.15–0.30 mm/rev feed; use a floating holder or verify runout ≤ 5 µm, and never reverse the spindle while the reamer is in the hole.

| Cast iron | Dry or minimal emulsion (MQL acceptable) |
| Aluminum | Emulsion or kerosene-based lubricant |
8. Operating Guidelines
- Ream immediately after drilling while the setup is undisturbed
- Use a floating reamer holder or ensure runout ≤ 5 µm
- Never reverse the spindle while the reamer is in the hole
- Feed in smoothly; retract at 2× feed with the spindle on
- Flood coolant continuously
9. Troubleshooting
| Problem | Cause | Solution |
|---|---|---|
| Oversized hole | Runout / built-up edge | Check holder; increase Vc; lubricant |
| Chatter marks | Low rigidity | Shorten overhang; reduce Vc |
| Poor finish | Stock too high / worn reamer | Reduce stock; replace/recondition |

13. Frequently Asked Questions
Q: What hole tolerance does Ø16 mm produce?
A: H7 / IT7 class with Ra 0.4–0.8 µm finish when run at ≤ 5 µm runout with correct stock allowance.
Q: How much stock should I leave for Ø16 mm?
A: 0.15–0.30 mm on diameter — pre-drill ≈ Ø15.75 mm.
Q: Can I reverse the spindle to retract?
A: Never — retract at 2× feed with the spindle still turning forward; reversing destroys the edges.
Q: Why is my reamed hole oversized?
A: Runout or built-up edge — check the holder, increase Vc slightly, and improve lubrication.
Q: Ream immediately after drilling?
A: Yes — ream in the same setup while alignment is undisturbed for best position accuracy.
