What size of line boring machine should I choose?
With a range of line boring machines available, selecting the right size is crucial. No single machine can precisely cover all diameters, so it's essential to consider the specific types of jobs you'll be performing.
What boring bar length should I specify?
Choosing the correct boring bar length depends largely on the nature of your projects. Note that for smaller diameter boring bars, longer bars pose a greater risk of sagging.
What are the lead times for line boring machines?
Lead times vary based on machine size and stock availability. Planning ahead is essential, as it can take several weeks from payment receipt to machine delivery. Each machine package is custom-made from a range of available options.
Can DIG-DOG supply a machine in my area?
Yes, our portable boring machines are exported worldwide, ensuring global reach and accessibility.
What maintenance is needed?
With proper care, the line boring machine promises years of reliable use, consistently delivering precise results. Routine maintenance involves simple cleaning, debris removal, and regular oiling.
