Gühring RT100 Drill Cross-Reference
Gühring's RT100 is a family of solid carbide drills — universal (U), stainless (VA), titanium/ISO-S (T), high-feed (HF), reinforced/deep (R) and extra-performance (XF) variants, most with through-coolant. Round tools have no shared ISO code, so a like-for-like competitor drill is matched on application class plus parametric geometry (diameter, point angle, flute and overall length, coolant, coating), not on a common code.
Treat equivalents as application-class starting points and verify feeds and speeds on a sample part: a cross-reference matches the drilling job, not the exact tool life.
| RT100 variant | Application | Walter Titex | Sandvik | Mitsubishi | Seco | Kennametal |
|---|---|---|---|---|---|---|
| RT100 U | Universal P/M/K/N/S, through-coolant | DC170 Supreme | CoroDrill 860-GM | MVS | Feedmax | HPX / KenDrill HP |
| RT100 XF | Extra tool life, universal+ | DC170 / DC180 Supreme | CoroDrill 860-GM | MVS (DP1020) | Feedmax | HPX |
| RT100 VA | Stainless (ISO M / K) | DC160 / DC170 (M grade) | CoroDrill 860-GM | MWS / MMS | Feedmax-MS | KenDrill HP |
| RT100 T | Titanium / ISO-S / HRSA | DC170 (S grade) | CoroDrill 860 (HRSA) | MHS | Feedmax HRSA | KenDrill HP HTA |
| RT100 HF | High feed, short (3×D) | DC150 / DC160 | CoroDrill 860-GM | MVS 3×D | Feedmax short | HPX short |
| RT100 R | Reinforced / deep (7×D+) | DC170 long (5–8×D) | CoroDrill 860 long / 862 | MVS 10–12×D | Feedmax long | HP Deep Hole |
Equivalents are matched on manufacturer application positioning. Where a variant (HF, T) has no dedicated competitor catalog line, the universal series with the matching geometry or grade option is named — no invented series. Mitsubishi WSTAR split: MVS universal, MWS / MMS stainless, MHS hardened, MNS aluminium, MCS composite. Walter range runs DC150 Perform → DC160 Advance → DC170 / DC180 Supreme.
| Tool | Ø | OAL | Flute | Point | Coating | Order code |
|---|---|---|---|---|---|---|
| Gühring RT100 U | 12.0 | 163 | 98 | 140° | nanoFIRE | 616 |
| Walter Titex DC170 | 12.0 | 163 | 96 | 140° | TiAlN (AlCrN) | 6745428 |
Near-identical geometry from live catalog data: overall length 163 = 163 mm, flute 98 ≈ 96 mm, point 140° = 140°, both solid carbide, both through-coolant. This is a parametric match at one diameter, not a claim of identical tool life. Dimensions in mm.
| RT100 variant | Point | Length class | Coating | Best for |
|---|---|---|---|---|
| RT100 U | 140° | ~5×D (OAL 103, flute 49) | TiN | universal P/M/K/N/S |
| RT100 VA | 135° | 12×D (OAL 190, flute 133) | PERROX (uncoated substrate) | stainless, deep holes |
Same Ø10 mm, but the universal and stainless variants differ in point angle, length class and coating (live catalog data). Match the competitor equivalent to the RT100 variant, not only the diameter — a universal drill is not a drop-in for the stainless deep-hole job.
Solid carbide drills across brands share the same standardized parametric fields (DIN 4000-81 / ISO 13399): cutting diameter, point angle, flute length, overall length, coolant type, shank and coating. A competitor drill is an equivalent when its application class matches the RT100 variant and its geometry overlaps at the target diameter. Grade names, availability and exact feeds vary by manufacturer and region — confirm on the manufacturer datasheet and a test part before production.
