The two bits in the set work as a pair: one bit produces the tongue profile, a protruding V-shaped tongue, while the other produces the groove profile, a V-shaped groove, ensuring precise fitting between boards. Compatibility with thicknesses from 19.05 to 25.4 mm covers the most common flooring boards and cladding panels. The set also allows more elaborate joints to be created with multiple passes, combining the two profiles in different sequences to obtain more complex joint geometries.\u003c\/p\u003e\n\u003ch3\u003eKrollit logistics and support\u003c\/h3\u003e\n\u003cp\u003eShipping in 3–5 working days from the Krollit warehouse in Monteforte Irpino (AV).

The two bits work as a pair: the first bit cuts the tongue profile, the protruding V-shaped tongue, on one edge of the board; the second bit cuts the groove profile, the V-shaped groove, on the edge of the adjacent board. The two boards fit together by joining tongue and groove. The operation requires two separate passes, one for each profile type, with adjustment of the parallel fence between the two passes.\u003c\/p\u003e\n\u003ch3\u003eDoes the set work on boards of any thickness?\u003c\/h3\u003e\n\u003cp\u003eThe M142 set is sized for panel thicknesses from 19.05 to 25.4 mm, corresponding to the most common flooring boards and wall cladding panels. For thicknesses outside this range, the joint is not correctly centered and loses precision.\u003c\/p\u003e\n\u003ch3\u003eIs it mandatory to use the parallel fence on the router table?\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer recommends use with a parallel fence on a router table. The fence ensures that each pass is parallel to the edge of the board and that the routing depth is repeatable on all pieces. Without a fence, the risk of variation between pieces increases, compromising the precision of the final joint.\u003c\/p\u003e\n\u003ch3\u003eCan the M142 set also be used on CNC?\u003c\/h3\u003e\n\u003cp\u003eYes, the M142 is compatible with CNC routers. The 12 mm shank is standard on benchtop CNC spindles. The laser marking on the shank includes the recommended maximum RPM as a reference for programming the spindle speed.\u003c\/p\u003e\n\u003ch3\u003eCan the bits in the set be resharpened separately?\u003c\/h3\u003e\n\u003cp\u003eYes. Each bit in the set can be individually resharpened at a specialized center. The HW cutting edges are 2 mm thick, sufficient for multiple cycles. After resharpening, it is necessary to check that the tongue and groove still fit correctly, since removing material from the cutting edge slightly changes the profile dimension.\u003c\/p\u003e\n\u003ch3\u003eIs the included bearing used for template work?\u003c\/h3\u003e\n\u003cp\u003eThe 15.8 mm diameter bearing is included in the set and can be used to follow a template. Alternatively, an additional bearing can be mounted on the shank with a stop collar, not included, or a guide bushing can be used on a handheld router, although handheld use is not recommended for bits of this diameter.\u003c\/p\u003e","brand":"igm","offers":[{"title":"Default Title","offer_id":53181102522696,"sku":"M142-00121","price":169.84,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/2139\/0920\/files\/Set_frese_IGM_M142_maschio_e_femmina_per_incastro_a_V_D50_8_mm_gambo_12_mm_HW.jpg?v=1779807881","url":"https:\/\/www.krollit.com\/products\/set-frese-igm-m142-giunzione-v-maschio-femmina-d508-s12","provider":"Krollit","version":"1.0","type":"link"}
