The BAUER 205421 replacement tooth is an aftermarket round shank drilling tooth designed for cross-reference applications corresponding to the BAUER RSM-D 17×30 configuration.
BAUER's Service Catalog identifies Item No. 205421 as RSM-D 17×30, with the long description RSM-38-50-17×30-131-CL. In this designation, the catalog identifies a 17 mm shaft diameter, 30 mm tungsten-carbide diameter, 38–50 mm body combination, 131 mm total tooth length, and CL long clamping-sleeve fixing configuration.
For contractors, drilling-tool distributors, and maintenance departments, the purpose of an aftermarket replacement is straightforward: maintain dimensional compatibility, restore cutting performance, and reduce equipment downtime without automatically requiring an OEM purchasing channel.
Why a Reliable Replacement Tooth Matters in Foundation Drilling
A drilling tooth is a relatively small component, but its condition directly affects the interaction between the drilling tool and the formation. When a tooth becomes excessively worn or damaged, operators may experience:
- Reduced penetration rate & increased drilling resistance
- Uneven cutting, heavier machine vibration, and abnormal holder wear
- Higher fuel consumption, frequent tool changes, and unplanned maintenance
For a foundation drilling contractor, the real cost of a failed wear component equals: Replacement part cost + labor + machine downtime + transportation + lost drilling productivity + secondary tool wear. This is why professional procurement should focus on fit, material consistency, and manufacturing quality.
BAUER 205421 RSM-D 17×30: Identification and Cross-Reference

Round Shank Foundation Drilling Tooth Construction
A typical round shank foundation drilling tooth consists of two major functional parts:
- High-Strength Steel Body: Provides structural connection. For custom production, 42CrMo alloy steel is specified to withstand repeated impact, compression, bending, and severe vibration.
- Tungsten Carbide Cutting Tip: Delivers primary rock-fracturing performance. Available with high-grade tungsten carbide tips designed to maintain hard cutting edges under abrasive conditions.
How to Verify Compatibility Before Ordering
Before purchasing replacement teeth, workshop engineers should perform a simple verification:
- Step 1: Record existing part numbers (e.g., BAUER Item No. 205421 / RSM-D 17×30).
- Step 2: Measure shaft diameter, carbide diameter, overall length, and collar dimensions.
- Step 3: Inspect the holder for enlarged mounting areas, deformation, or cracks.
- Step 4: Verify the retention system (CL long clamping sleeve configuration).
