August Beck Precision Holemaking Systems
High-performance monoblock, expandable, modular, DIN, and custom stepped reaming solutions.
High-speed fine boring with unequal flute spacing that eliminates vibration chatter, producing ground/honed quality bores.
Standardised multi-bladed reamer family with fixed, expandable, or finely adjustable variants sharing uniform dimensions.
Engineered with targeted coolant lubricant guidance to eliminate thermal shock at cut entry in steel and ductile cast iron.
Higher blade count with peripheral streamlined coolant ducts. Replaces secondary honing in hydraulic spool valve bodies.
Selective direct coolant channels and specialized coatings for steel, aluminum, CFRP, GFRP, and hard machining up to 62 HRC.
Taper and plane-face joint with integral threaded journal guaranteeing radial run-out ≤ 5 µm; swap heads directly inside machine.
Just 6 connection sizes cover Ø 8 to 40 mm across standard, short, and extended lengths with internal high-pressure coolant.
Standardized DIN 212 / DIN 8093 reamers for small to medium batch runs, offering high wear resistance and instant stock delivery.
Manufactured strictly from premium European cobalt high-speed steel for tough, interrupted-cut machining and shell reamer arbors.
Pre-reaming core opening tools with chip space ground quality, plus 180° counterbores for socket cap screw recesses.
Square drive shanks for manual tap wrenches, enabling on-site assembly realignment, repair reaming, and taper pin fits.
Application-specific multi-step reamers designed to combine roughing, chamfering, and finish calibration into a single pass.
