Drill Bits
The UNION TOOL range of PCB Drills are produced on proprietary equipment that is both designed and built in-house.
This strategy has enabled the engineers to design in the highest levels of product quality, utilizing over 40 years of knowledge and experience.
This advantage has enabled Union Tool to install innovative, industry leading equipment such as the DIS (Automatic Optical Inspection System for drill point control) much earlier than competition. It also ensures much quicker adaptation to the demands of technology and capacity, such as the growth in micro drills.
Through this strategy UNION TOOL has attained and maintains its number one market position.

MD-MC-MV- MCV-MCW-MHW Drill series - Dia. 0,050 ~ 0,275 mm
Meeting the demands of surface mount technology (SMT) electric printed circuit boards, these microdrill series are used for through holes and blind via hole drilling. Made from hyperfine grain carbide alloy, this is an extremely robust product range.
UC-UV-UW-UHW Drill series - Dia. 0,30 ~ 0,75 mm
Under cut type drills for a wide range of applications that need either small through holes or via inter connects. The design balances the needs for improved inner hole wall quality, while maintaining good hole registration accuracy. Made from a tungsten carbide alloy with a high modulus of elasticity, this range is perfect for today’s demanding high density multi-layer boards.
ST-STB-UM35-UM30 Drill series - Dia. 0,60 ~ 3,175 mm
ST series: universal and economical drill for a wide range of materials.
Dia. 0,60 ~ 1,60 mm
STB series: universal and economical drill for a wide range of materials.
Dia. 1,65 ~ 3,175 mm
UM35 series: undercut design to improve the hole wall quality in multi-layer boards.
Dia. 0,80 ~ 1,60 mm
UM30 series: undercut design to improve the hole wall quality in multi-layer boards.
Dia. 1,65 ~ 3,175 mm
ID30C Drills - Dia. 3,20 ~ 6,50 mm
ID30C Series: A unique drill with a “chip breaker” to help prevent “bird nesting” and a web thinning that greatly reduces the thrust load on the spindle.
* Big diameters 6,55 ~ 8,00 mm upon request
SX24 - SX Drills - Dia. 0,50 ~ 3,175 mm
This undercut drill has special geometry designed for slot drilling. Using a web taper design for maximum rigidity, the drill can be used at high in-feed rates for increased productivity. Even when slots requiring length two times of drill diameter, this range of high precision drills gives excellent results.
SX24 series: Dia. 0,50 ~ 1,60 mm
SX series: Dia. 1,65 ~ 3,175 mm
