Type of drill	Diameter range	Applications
TCR-UCD –Coated single flute drills		PVD single coated flute drills with new geometry and extra long flute for better accuracy in high aspect ratio PCB and hard material.
UCY1 – Undercut drills	0.075 – 0.4 mm	Improved positional accuracy and increasing tool life Higher productivity with stack-up drilling.
MD – Micro drills	0.075 – 0.45 mm	TCT MD series drill can meet the increasing requirements of PCB/BGA shops due to its high productivity. MD is made of high wear resistance material on cutting lip especially under high infeed. Besides, stronger geometry design also can provide an excellent drilling accuracy performance.
UC – Undercut drills	0.6-1.2 mm	TCT UC series drill with undercut type can perform an excellent hole-wall quality. The major purpose of this type is to prevent from increasing cutting heat. UC series can solve the smear problem during drilling process on multilayer boards.
UCC – Undercut drills	1.25 – 1.6 mm	TCT UCC series drill with undercut type can perform an excellent hole-wall quality. The major purpose of this type is to prevent from increasing cutting heat. UC series can solve the smear problem during drilling process on multilayer boards.
ST/STC – Straight drills	0.5-3.175 mm	TCT ST series drill with straight type can be used for different kinds of board materials, such as FR-4 (generally used), CEM-1,CEM-3,…etc.
RD – Reverse drills	3.2-7 mm	TCT RD Reverse drill series drill with overlapped relief face geometry promotes longer tool life.
