FAMAG Bormax prima lungo Serie 1614

FAMAG Bormax prima lungo Serie 1614

The FAMAG Bormax prima lungo Serie 1614 combines the function of a Forstner drill bit and a counterbore.

There are various ways of joining construction timber. One traditional and popular method is the use of bolted connections using threaded bars or bolts, washers and nuts. Standards stipulate the dimension of the washer depending on the choice of the threaded bolt.

If a concealed joint is desired or required by regulations, the washer and nut must be embedded in the wood. The joiner will usually drill a through-hole with an augur drill bit into the wooden beam to correspond to the diameter of the threaded bolt. As a rule, the beam will be softwood or construction timber. To embed the washer/nut the joiner will use a counterbore drill bit. Counterbore drill bits are a type of cylinder head drill bit and differ from classical Forstner or cylinder boring bits in that they do not possess a fixed centring point. Instead they have a locating hole into which a pilot drill bit or guide pin can be inserted.

We offer counterbores with 19 different diameters as standard. The smallest diameter is 20 mm and the largest 120 mm. The locating hole is 8 mm in diameter on counterbores from 20 to 40 mm in diameter and 10 mm on larger counterbores. We offer guide pins 8 to 22 mm in length to fit either of the locating holes. Incidentally, FAMAG always supplies its guide pins slightly undersize. This results in very easy and precise guidance without noticeable friction in the predrilled hole.

Guide pins give perfect guidance during counterboring so that freehand drilling of larger diameters is easier than with a drill bit having a fixed centring point. As an alternative to guide pins there is a choice of pilot drill bits: 8 mm for counterbores up to 40 mm in diameter and 10 mm for drill bits from 45 mm in diameter. Basically, you can insert any wood drill with 8 or 10 mm diameter shank. The advantage of the FAMAG pilot drill bit is that the shank is provided with drive flats for improved power transmission. With a pilot drill bit in position you can drill and counterbore in one operation and save the time spent on a separate predrilling. This tool configuration also lets you drill into a workpiece at a slant.

New on the Bormax 2.0 prima long are the circumference cutters with cooling fins. The spiral grooves significantly reduce friction in the borehole. The Bormax 2.0 prima long will keep a cool head even with heavy-duty use.

Counterbores are often used in larger diameters. The feed force increases with the diameter. Because these tools are used freehand, it is desirable that these forces are reduced as far as possible. This is achieved by the new Bormax 2.0 geometry! On both of the main cutting edges there are mutually offset chip breaker grooves that enable faster and easier boring. This reduces the feed forces substantially. The counterbore drill bit is supplied together with a centring drill bit (as seen in the picture). The depth of the centring drill bit can be set so that it protrudes only a small amount. Alternatively you can mount the pilot drill bit so that it protrudes a significant amount. The further it protrudes, the better the guiding effect; with a powerful cordless drill driver you will be able to drill freehand boreholes in softwood up to 100 mm in diameter!
