During the IPMS USA Nationals this year, John Vojtech was kind enough to provide several of his tools from Unique Master Models (UMM) to the IPMS Review Corps, and this was one of the items I was fortunate enough to receive. Consisting of an ergonomic plastic handle, eight drill bits, and a bit removal tool, everything you need for drilling small holes is provided in one convenient set.
Measuring 120mm in length, the handle is quite comfortable to hold and the drill bits easily slide into an opening in the end. The drill bits are designed with a grooved base that securely locks into the handle. The bits are 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1.0mm in size, which are sizes commonly called out in kit instructions, and UMM recommends this set for fine detail work. The wedge-shaped removal tool aids in quickly changing out the bits.
