Rent, Buy Used or Buy New: Mag Drill Cost Worksheet

Calculate the complete rental job

Request a quote for the correct capacity and accessories, then include collection or delivery, the rental period, consumables and any applicable fees stated in the agreement. Ask what happens if the job runs late or a cutter is damaged. Do not assume cutters are included simply because the machine is described as a drilling kit.

Rental is especially worth investigating for a one-off capacity or clearance requirement. Confirm availability for the actual dates before building the project schedule around it. If the supplier proposes an alternative model, repeat the tooling and mounting checks.

Inspect a used purchase as a system

Ask for the exact model, identifying label, service history and a list of included components. Locate its manual and parts information before paying. Missing guards, holders, pins or restraint components may create more than a minor shopping inconvenience.

Arrange inspection or assessment by someone qualified to evaluate that machine, particularly the magnetic base, electrical condition and feed mechanism. Do not accept a brief motor-running video as a complete condition test. Ask whether holders or other parts have been modified and how replacement parts will be sourced.

Price the benefit of buying new

A new purchase may provide a clearer starting condition and documented package, but verify the seller’s terms and the exact items supplied. Review warranty eligibility, exclusions and the service route for the offer being considered. Do not assume coverage transfers with a used machine or applies equally to every seller.

Manufacturer product pages and parts catalogs help identify what a complete setup should contain. Use them as a reference, then reconcile that list with the specific sale. Keep purchase records and model identification together.

• Compare the same hole capacity, depth and cutter system.
• Include tooling and transport in every option.
• Treat condition assessment and service access as real costs.

Use a break-even worksheet

For a simplified estimate, divide net ownership cost by the rental cost avoided per comparable job. Net ownership cost includes purchase, expected maintenance and tooling differences, less a cautious resale estimate if appropriate. This is a planning model, not a resale or reliability forecast.

For example, hypothetical net ownership cost of $900 divided by $150 avoided rental cost suggests six comparable jobs before ownership breaks even. Replace both figures with actual quotes and avoid counting the same consumables twice. If future work is uncertain, test the calculation at fewer jobs before making the purchase.
