CoroReamer® 835

CoroReamer 835 is optimized for specific materials. Internal coolant and extremely unequal spacing of the cutting edges are two features that promise really close hole tolerances and high-quality surface finish.

Correct diameter

Ensure that the pre-drilled hole has the correct diameter for stock removal allowance.

Rigid workpiece

The workpiece must be held rigid and the machine spindle should have no play.

Short overhang

Keep the tool overhang from the machine spindle to a minimum.

Lubrication

Use recommended lubricants.

Application tips

Initial considerations

Initial considerations

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

Troubleshooting

Troubleshooting

Is your spindle or tool run-out too high? Do you have wrong cutting data, or are you perhaps wondering how to avoid a built-up edge during your reaming process? Check out our reaming troubleshooting guide.
