What size of line boring machine should I choose?

With a diverse range of line boring machines available, selecting the right size is crucial. No single machine can accurately cover all diameters, hence it's essential to consider the specific types of jobs you'll be performing.

What boring bar length should I specify?

Selecting the appropriate boring bar length depends predominantly on your job requirements. It's important to note that for small diameter boring bars, longer bars increase the risk of sagging, which can affect performance.

What are the lead times for line boring machines?

Lead times vary based on the size of the machine and stock availability. As each machine package is custom-made, it's advisable to plan ahead since it can take several weeks from payment receipt to delivery.

Can DIG-DOG supply a machine in my area?

Absolutely, our portable boring machines are exported globally, ensuring we can supply to your area.

What maintenance is needed?

With proper care, the line boring machine delivers years of reliable, accurate performance. Routine maintenance involves simple cleaning, debris removal, and oiling, ensuring consistent results every time.
