The design principle is simple: the workpiece is clamped manually, the router makes one cut per stroke, the operator releases and repeats. The 32,000 rpm and 0.85 kW motor ensure clean routing on standard wood types (oak, fir, beech) without chipping. The 6 mm cutter holder diameter accommodates standard W-2 dovetail cutters in various lengths depending on the material. The adjustable guides allow precise workpiece positioning, with a maximum profile width of 185 mm and a clearance of 95 mm. In Krollit customers' workshops, it is chosen by artisanal carpentry shops that produce frames, segmented arches, windows, custom structures, and by carpenters who perform glue-free dovetail joints for small and medium series. Its 10 kg weight and compact dimensions of 400×620×535 mm make it transportable to construction sites for on-site assembly and repairs.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe KNF 1 is the entry-level model in Bernardo's KNF family for dovetail joints. Above it is the KNF 2 (weight 16 kg, dimensions 400×500×730 mm), which performs two cuts simultaneously in a single operation, sized for joints on wider elements (handrails, corner benches, arches). The practical difference between KNF 1 and KNF 2: the KNF 1 performs one cut per cycle (simpler, more economical), the KNF 2 performs two (faster for repetitive symmetrical work). Same 0.85 kW motor and same 6 mm cutter holder diameter: the difference is in the machine's geometry (single cutter vs. double cutter). For standard production of simple frames and structures, the KNF 1 is correctly sized. For series production of symmetrical joints on large pieces, the KNF 2 halves the time. For general wood routing (not just dovetail joints), the Bernardo range offers vertical spindle moulders Toupie T (T 500 PR, T 600 R, T 650, T 1300, T 1300 E) with different purposes.\u003c\/p\u003e\n\u003ch3\u003eKrollit logistics and support\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping in 5-9 working days (7 days to the South).

It is the traditional technique for solid wood frame joints.\u003c\/p\u003e\n\u003cp\u003eThe dovetail joint uses the angle (typically 7-12°) between the joint walls: once inserted, the piece cannot slide back due to its geometry. With cutters of adequate length for the material and correct depth, the connection achieves strengths comparable to solid wood. For very hard tropical woods, it is recommended to check the cutter length and adjust the feed speed.\u003c\/p\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eWhat is the difference with a standard spindle moulder?\u003c\/summary\u003e\n\u003cp\u003eToupie T machines are for general routing (profiling, tenoning, grooving, shaping).

Cutters that are too long on hard woods can break due to heat generated by friction; cutters that are too short on soft woods do not utilize the available depth of the machine.
