Molybdenum Coated: molybdenum cools and lubricates the bit. The bit stays sharper longer because the heat treatment lasts longer. The bit ejects chips and bores faster than ordinary bits and binds less, even in wet or resinous woods.
Deeper lands: for a stronger less flexible bit.
Extensions: two recesses on shank to receive extension set screws.
HL-403 及 HL-457 木工直攻鑽具備耐用結構與順暢排屑機能,是木工裝潢與結構作業的理想工具,支援長時間施工與高頻率使用。
