Off-center drilling, damaged sealing surfaces and high physical workload are common challenges in the conventional production of pipe outlets for mechanical tees in sprinkler systems. Norwegian company Snap Drill AS has developed a handheld pipe drilling machine with an automated feed mechanism to address these issues. In practical operation, the tool can reduce working time by up to 50 percent compared to manual methods.
Operating principleThe tool secures itself directly to the pipe using a self-centering clamping jaw. An automatic feed system with a slip clutch applies the necessary pressure, eliminating the need for manual force or torque support.
As a result, sudden jamming of the hole saw is prevented by design. An integrated spirit level enables precise alignment, while a pilot drill is no longer required.
The drilling process produces consistently centered holes with clean edges. The technical advantage over manual drilling becomes especially apparent in tool life: conventional hole saws typically last for 10 to 15 holes in manual operation, whereas the automated SnapDrill system achieves approximately 400 holes.
Field applicationsAt Encore Fire Protection in the United States, SnapDrill delivered measurable results in a 46,500 m² logistics facility. More than 5,000 holes were completed with minimal wear, resulting in time savings of approximately 250 labor hours — a major advantage in environments facing labor shortages and tight project schedules.
At Stavanger Airport in western Norway, stainless steel pipes were used due to demanding coastal conditions. SnapDrill also proved effective with this challenging material.
“Stainless steel is particularly difficult to cut. The team benefited significantly — the drilling is always centered with a clean surface, ready for welding,” said Martin Talgø, Managing Director of SnapDrill.
André Thielemann of Calanbau Brandschutzanlagen GmbH, a German fire protection specialist, described the practical benefits: “In sprinkler installation, where hundreds of outlets often have to be produced quickly, a tool like this makes a real difference. The holes are precise, the work is far more comfortable, and ultimately it saves a considerable amount of time.”
