Policies and Procedures

No-Fault Return Period - We will accept merchandise for return that was purchased from Think & Tinker, Ltd / PreciseBits.com within 30 days of receipt by the customer with no restocking fee. 

Please note that ALL returned items must be inspected and run through QC before any refund is made. This can take as long as 2 weeks, depending on the time of year and the quantity of merchandise being returned.

NOTE: Items returned after the 30-Day return period above may be subject to a 20% QC / restocking charge.

The merchandise must be:

  • in new and unused condition. Tools that show any signs of use will not be accepted.
  • returned with a copy of the original paperwork. If we don't know who returned the tools, it is VERY hard to process a refund.
  • in the original packaging. By this we mean the plastic tool packs, not the external corrugated box.
  • in particular, end-mills, v-tips, and tapered stubs MUST be returned in the plastic packaging showing the handwritten production batch number (aka lot number). Without the batch number we have no way of recertifying these bits, regardless of their condition.
  • shipped prepaid to our physical address (UPS or FedEx) or to our PO Box (USPS). We do not accept returns via COD or billed to Think & Tinker, Ltd / PreciseBits.com in any way.
  • be accompanied by an RMA number assigned by Think & Tinker, Ltd / PreciseBits.com. Call 719 488-9640 for a return authorization

Merchandise may be returned for the following reasons.

  • "No Fault" returns -
  • If you are not satisfied with the tools that you have received, for any reason, you can return any of our products back to us, in the original packaging, within 30 days of the invoice date, and we will refund your money. All you have to pay for is the shipping and for any tools you do not return.(Exceptions may apply for special orders. See below.)

  • Returning defective items -
  • If you receive an item that is inoperable, but has no apparent damage, it is considered defective. Defective merchandise may be returned to us within 30 days of purchase, as long as it is in new and unused condition. Prior to returning the item, please call PreciseBits technical support (719-488-9640, 08:30 to 16:30 Mountain Time) to discuss how the product is being used. Many times in the past we have found that, what appeared to be a defective or non-fucntional item, was not installed properly or simply being used incorrectly.

  • Returning damaged items -
  • If a shipment arrives at your door with apparent shipping damage, please refuse the delivery and note on the refusal form that the external packaging had obvious damage. If you have already accepted delivery and then find shipping damage:

    • please call or e-mail us immediately
    • save all packaging material and paperwork
    • do not throw anything away

    If you return damaged or defecteve merchandise before contacting us, you will jeopardize our chances of making a claim with the shipping company, and you may not receive credit for the return.

Special Orders - If your purchase constituted a "Special Order" defined as a purchase of:

  • any tool other than those regularly offered for sale through our website
  • a quantity of any tool, or group of tools that require a special production run, or
    • a quantity of any tool, or group of tools that require special, non-standard or custom depth-ring placement, or
  • any product that is designated a "Special Order" at the time of purchase

you order is NOT covered by the provisions of our No Fault Return policy and may only be returned at the sole discretion of Think & Tinker, Ltd.. Such Special Orders will be subject to a 10% restocking charge in addition to the recapture of any credit card fees that might apply.
