BESCHREIBUNGDESCRIPTION

Bei diesem Werkzeug hsindelt es sich um einen SPEZIALBOHREB FÜR CÜüTKES MATERIiT. von 0,5 bis 4mm Starke .This tool is a SPECIAL HOLE FOR CÜüTKES MATERIi T. from 0.5 to 4mm thick.

Der SPETZIAL30HRER FÜR DÜNNE METALLE besitzt die Sigensehaft, einwandfreie runde Löcher In Bleche jeder Art wie Kupfer, Alu, Stahlblech usw. gefahrlos und genau auf ein bestimmtes Maß zu bohren.The SPETZIAL30HRER FOR THIN METALS has the Sigensehaft, Perfect round holes In sheet metal of any kind such as copper, aluminum, sheet steel, etc. safely and precisely on a specific one Drill dimension.

Der SPEZIALBOHRER FÜR DÜNNE METALLE besteht aus gehärteten Werkzeugstahl .The SPECIAL DRILL FOR THIN METALS is made of hardened tool steel.

DSR Unterschied dieses SPEZIALBOHRER ?ÜR IiOMIE METAMJS gegenüber eines normalen SPIRALBOHBJ?^ L/tateht dar in IDSR difference of this SPECIAL DRILL? ÜR IiOMIE METAMJS compared to a normal SPIRALBOHBJ? ^ L / tateht is in I.

mit einem normalen SPIRALBOHRER ab der lOam Größe, kann man kein einwandfreies rundes Loch in Blech bohren, weil dieser SPIRALBOHRER von der BOHRSPItZS aus nach aueen bohrt und das Loch daher dreieckig wird· Sagegen der SPEZIALBOHBIR FUR SOHNS MSTALIiS eine FÜHRUNGSSPITZE (1) und auserden nooh zwei SCHNEIDBSPITZEN (2) hat. Sas heißt:with a normal TWIST DRILL from lOam size, can you do not drill a perfect round hole in sheet metal because this TWIST DRILL will drill outwards from the DRILLING POINT and the hole therefore becomes triangular · On the other hand, the SPEZIALBOHBIR FUR SOHNS MSTALIiS has a GUIDE POINT (1) and auserden nooh has two CUTTING POINTS (2). Sas means:

Bei einem Arbeitsablauf setz man die FÜHRUNGSSPITZE (1) «ie bei einem; normalen SPIRALBOHRER in die Kärnung oder in ein 1-2mm vorgebohrtes Loch.During a work process, set the LEADING TIP (1) «ie at a; normal TWIST DRILLS in the Kärnten or in a 1-2mm pre-drilled hole.

Nachdem die FÜHRUNGSSPITZE (1) die Körnung oder da« vorgebohrt« Loch zu einem Trichter ausgeweitet hat , schneidet der SPKIAL-BOHRER FÜR DÜNNE METALLE mit den zwei AUSENLIEGEIfDEN SCHNEIDE-SPITZEN (2) von ausen nach innen. Daher ein einwandfreies , rundes und fast gradloses Loch·After the GUIDE TIP (1) has "pre-drilled" the grit or If the hole has widened to a funnel, the SPECIAL DRILL FOR THIN METALS cuts with the two EXTERNAL CUTTING POINTS (2) from the outside to the inside. Hence a perfect, round and almost straight hole
