Series B901 HSS Straight Shank Machine Reamer - Metric 
Flute geometry 7º Left Hand Spiral.
Bevel Lead 45º a side.

Used for opening out and finishing existing holes to H7 tolerance in most ferrous and non-ferrous metals.

To obtain the best results when using reamers it is essential to make them 'work'. It is a common fault to prepare holes for reaming with too little stock left in. If insufficient stock is left in the hole before reaming then the reamer will rub quickly, show wear and will result in loss of diameter. It is equally important for performance not to leave too much stock in the hole.

HSS Spiral Flute straight shank machine reamer for opening and finishing existing holes to H7 tolerance.
Suitable for most ferrous and non-ferrous materials.
6° helix, left hand spiral for excellent surface finish.
Manufactured to BS328 standard.
