Product codes
Product codes are a valuable tool to describe and iden-tify the product. In the code structure we have tried to describe the product features with Alfa-numerical system
and not always 100% logical, but with the attached key you will be able find the product you are looking for or and alternative product.

Model -40All-round bit for medium-hard to hard rock. Side flushing only. Inclined front buttons.
Model -41, short skirtAll-round bit for medium-hard to hard rock. Front and side flushing. Inclined front buttons.
Model -56All-round drill bit for medium-hard to hardrock formations. Front and side flushing.
Cross-type bitFor hard and abrasive rock. Front and side flushing.
Please observe that all button bits are manu-factured over-sized 0.5–1.0 mm, meaning that for example a 36 mm bit is at least 36.5 mm as new. This is done because of the fast initial wear on button bits.
When it is of importance, also consider that the hole is always 1–3 mm bigger than the bit dimension depending on rock formation.

Model -37-662+2+2 gauge buttons, 3 front buttons.
With � full- ballistic buttons and excellent flushing with extra flushing grooves, model -��-�� offers extremely good penetration rate in soft rock.
Model -392+2+2 gauge buttons, 3 smaller front buttons.
With its larger gauge buttons, model -�� is ideal for abrasive rock. Available with spherical buttons.
Model -412+3 gauge buttons, 2 front buttons.
For medium-hard to hard rock formations. Available with spherical or ballistic buttons. Inclined front.
Model -42Reaming bit. Dome-shaped front.
Model -�2 is a new alternative to traditional reaming equipment. Use in a pre-drilled pilot hole. Tried and tested with excellent results.
Model -562+2 gauge buttons, 2 smaller front buttons.
Traditionally used in hard rock forma-tions, model -�� delivers excellent pen-etration rate. Available only with spherical buttons.
Cross-type bit4 chisel inserts in cross formation.
Traditional insert bit for extremely abrasive rock formations. Ideal for soft formations that cause "snake-skin" problems for carbide. Produces straight holes but has lower penetra-tion than button bits.

Drill bit design
Model -27-30, -37-30
Please observe that all button bits are manufactured over-sized 0.5–1.0 mm, meaning that for example a 36 mm bit is at least 36.5 mm as new. This is done because of the fast initial wear on button bits.
When it is of importance, also consider that the hole is always 1–3 mm bigger than the bit dimension depending on rock formation.
