Tungsten Steel PCB Drill Bits with 0.1-1.2mm Blade Diameter for Circuit Board Assembly

These fixed shank carbide small drills provide precision drilling capability for electronic assembly applications, particularly circuit board fabrication and repair work. With tungsten steel construction and straight shank twist drill design, these tools offer consistent performance for creating clean holes in PCB substrates. Available in practical 10-piece packs, they provide immediate workshop readiness without requiring minimum quantity adjustments. The compact 36-38mm total length and 1.5-10.5mm useful cutting length make these drills particularly suitable for detailed work where space around components is limited.

Features and Construction

The drill bits feature a straightforward design optimised for electronic assembly applications, with construction details focused on precision cutting performance. The materials and dimensions are specified to support consistent operation in circuit board drilling scenarios.

Material and Build

Constructed from tungsten steel, these drill bits offer hardness suitable for cutting through circuit board substrates without immediate dulling. The fixed shank design with round handle provides a 3.2mm diameter contact surface for secure mounting in appropriate drilling equipment. As straight shank twist drills, they maintain consistent cutting geometry throughout their usable life, supporting repeatable hole creation across multiple workpieces.

Size and Practical Fit

With a total length of 36-38mm, these compact drill bits fit comfortably in precision drilling setups where space around electronic components is limited. The useful cutting length of 1.5-10.5mm provides sufficient depth for standard circuit board thicknesses without excessive protrusion that could interfere with adjacent components. The 3.2mm shank diameter ensures compatibility with standard collets and chucks designed for small precision tools.

Uses and Placement

These drill bits are specifically designated as circuit board drill bits, indicating their primary application area in electronic fabrication and repair environments. Their size and construction make them suitable for both professional assembly lines and workshop-based repair scenarios.

Event or Professional Use

In professional electronic manufacturing environments, these PCB drill bits support consistent hole creation for component placement across production batches. The availability in 10-piece packs allows workshop managers to maintain adequate tool inventory without excessive capital commitment. The two model ranges—covering 0.1-1mm and 0.3-1.2mm blade diameters—provide flexibility for different hole size requirements in circuit board design specifications.

Everyday Home Use

For electronics hobbyists and repair technicians, these compact drill bits enable precise work on circuit boards during modification or repair projects. The 0.05kg product weight makes handling comfortable during extended work sessions, while the straightforward design requires minimal specialist knowledge to operate effectively with appropriate drilling equipment.

Benefits and Buying Value

The practical benefits of these PCB drill bits centre on their specialised design for electronic assembly work and their packaging approach that supports both immediate use and workshop inventory management.

Reuse and Low Maintenance

The tungsten steel construction supports multiple uses before requiring replacement, while the straight shank twist drill design maintains consistent performance across drilling operations. With no complex moving parts or adjustable components, these drill bits require only basic care—primarily proper storage to prevent damage to the cutting edges—to maintain their functionality between uses.

Why Choose This Product

These fixed shank PCB drill bits offer a focused solution for circuit board drilling applications, with specifications tailored specifically for electronic assembly work rather than general-purpose drilling. The availability in defined 10-piece packs provides certainty about minimum quantities, while the two blade diameter ranges address different hole size requirements in circuit board fabrication. The compact dimensions and lightweight construction make them suitable for precision work where control and visibility are important considerations.
