Which cutting diameters are listed for NAM micro drills?
The catalogue lists NAM models from 0.1 to 2.9 mm in cutting diameter. Check the complete row for the flute length, shank diameter and overall length associated with the chosen size.
Should the holder match the cutting diameter?
Select the holder using the shank diameter d shown on the model row. The cutting diameter D and holding diameter are separate dimensions.
Does flute length establish the maximum drilling depth?
Lc identifies the fluted section of the tool. Confirm the permitted working depth and operating conditions for the selected model, workpiece and machine setup.
What should I check if a micro drill breaks during a trial?
Review the holder and alignment, tool projection, workpiece, hole depth and chip removal with the tool supplier. Record the trial conditions before changing the tool or machining cycle.
Are NAM micro drills supplied with internal coolant channels?
Confirm the coolant configuration for the selected model when ordering and specify the cooling arrangement available on your machine.
How can a distributor request a mixed-size quotation?
List each full NAM model and quantity separately. Include the destination and any drawing, inspection, labelling or packaging requirements so each purchase line is clear.
