Used and acclaimed by locksmiths and builders alike, the DBB Morticer has proved itself to be an invaluable tool for anyone regularly fitting mortice locks.

Below is a handy Q&A rundown on the product:

Q: What is included in the price of the DBB Morticer?

A: Every DBB Morticer Kit comes in a heavy duty case, the jig of your choice, self centring or adjustable stops, drive shaft, three wood cutters and an instruction manual.

Q: Are there any additional and special accessories for the DBB morticer?

A: Yes. Spare parts are provided for each individual piece of the Morticer.

Q: Do instructions come with the DBB Morticer?

A: Yes. A comprehensive instruction manual complete with illustrations and written instructions is provided. It is an easy-to-follow guide for either the novice or for the experienced professional.

Q: What cutters come with the jig?

A: Usually three popular wood cutters. Ask your supplier for precise details.

Q: What are the cutters made from?

A: Mortice wood cutters are carbide tipped. Plunging and aluminium cutters are HSS.

Q: Can the wood cutters be re-sharpened?

A: Yes. The instruction manual provides advice and instructions on sharpening.

Q: Can I plunge with the wood cutters?

A: Yes, four sizes of plunging cutters are now available.

Q: How deep can the jig cut?

A: 90mm with the Standard shaft (100mm without depth stop) and
170mm with the Long shaft (180mm without depth stop). Longer shafts are also available.

Q: What is the bearing system?

A: These are sintered bronze bushes impregnated with oil.

Q: How long do the bearings last?

A: Typically, they will last 200 to 300 lock installations.

Q: Are replacement bushes available?

A: They are available, but require specialist equipment to replace. Ordering a housing kit instead is recommended, which comes pre-assembled and takes just a minute to change over.

Q: What thickness of door will the jig suit?

A: Standard morticers will suit doors up to 55mm thick. For doors 55mm+ use the DBB/HK/S. Offset Morticers will suit doors up to 95mm thick, but this jig is not self-centring.

Q: Will the jig work on aluminium?

A: Yes, there are four cutters for aluminium doors.

Q: Are cutters for steel doors available?

A: No, not at present, but there are plans to develop some.

Q: Do I have to keep re-setting the jig when I take it off the door?

A: If the locks and door thicknesses are the same, you can use the tube clip at the top to create a “datum” for repeat work. Simply slide the clip down to the top clamp. This will enable the user to cut identical holes without any re-setting.

Q: Does the jig come with a drilling machine?

A: No, you have to provide your own.

Q: Is there a recommended drill specification?

A: 800 Watt, 13mm (1/2″) chuck and 2000 to 3000rpm is an ideal drill, but not SDS. Impact/hammer must be set to “off”.

Q: Can the jig be used to install electric locks?

A: Yes, there are two long drills and a long drill adapter to drill through the door for lock cables.

Q: How do I prevent the knots in doors forcing the long drill off-line?

A: Both long drills use special geometry so that it wants to stay on line.
