Reaming tools \ HSSE machine reamers H7
HSSE machine bottoming reamer
For universal use up to 1000 N/mm 2

HA
HSSE H7
0°
Application: Execution:
for cutting H7 fit tolerances with precisely defined ƒ straight-grooved, teeth around the circumference
drill spacings (tolerance of pre-drilling counterbal- with circular grinding chamfer to the duct
anced) on conventional machines and NC machine p. 134 p. 62 p. 703 p. 168
up to 1000 N/mm . the face cut overcomes the Advantage:
2
eccentricity between the bore and tool axis and does ƒ good bore hole quality (dimensional tolerance,
not follow the pilot hole. roundness, surface quality)
ƒ a groove is inserted for each to improve the supply
of coolant
