Multi‑Flute PCD‑Tipped Two‑Step Fine Boring Tool
(In stock)
| Product Name | Multi‑Flute PCD‑Tipped Two‑Step Fine Boring Tool |
| Model Number | Multi‑Flute, Two‑Step Adjustable Reamer (Gühring series; typical application for valve seat and guide bores) |
| Brand | Gühring KG |
| Category | PCD Tools / Fine Boring Tools – Cylinder Head Machining |
| Country of Origin | Germany (manufactured by Gühring KG, based in Albstadt‑Ebingen) |
| Material | Polycrystalline diamond (PCD) cutting edges on a multi-flute body with precision adjustability mechanisms (inner and outer tool bodies with integrated taper adjustment for the second step). |
| Applications | Efficient parent-metal machining of valve seat and valve guide bores in a single setting—ensuring tight circularity, form accuracy, concentricity, and long tool life in cylinder head production . |
Gühring’s multi-flute, PCD-tipped two-step reamer streamlines cylinder head machining by combining valve seat and valve guide bore operations in one setup. Featuring precision adjustability via a screw-actuated inner tool body and taper design, it maintains tight tolerances in circularity and concentricity while offering significantly extended tool life. Compared to single-flute reamers, this 6-flute variant allows machining at much higher cutting speeds—boosting feed rates and reducing cycle times by over 80 %, with up to 320 % increased cutting speeds.
