Description
The Vermaent Expanding Hand Reamers (HSS) are precision cutting tools manufactured from premium High-Speed Steel for superior hardness, heat resistance, and cutting performance. These reamers are designed specifically for finishing and sizing valve guide bores in cylinder heads to exact tolerances.
Unlike fixed reamers, expanding reamers allow the technician to fine-adjust the cutting diameter within a calibrated range, accommodating slight variations in oversized valve guides and achieving the precise bore diameter required for optimal valve stem clearance. HSS construction ensures longevity even when used on hard cast-iron or aluminium cylinder heads.
