Drill Stops used for pilot drilling and countersinking in one operation.

Countersinking for Deck screws.

For Terrassotec Ø 5 and 5.5 mm, Hapatec Ø 5 mm and Hapatec Heli Ø 5 mm

a) Drilling diameter x drilling depth

Pilot drilling is strongly recommended for fastening tropical woods/hardwoods. This is advisable even with the relatively easily splittable Douglas fir, and when screwing close to wood cut against the grain.

• Boring and countersinking in a single pass

• Screwing torque for inserting Terrassotec and Hapatec screws is greatly reduced, ie no more shearing of the screws, above all with the combination

• Perfect seat of the screw head
