TECWERK Step drill bit 4–12 mm, HSS, spiral flute, 9-step

The TECWERK step drill bit 4–12 mm is a precision-engineered stepped drill for fast, sequential hole-making across the 4–12 mm range, designed for secure clamping and consistent hole quality

• HSS, precision-ground, cross-cut tip
• Spiral flute for improved chip evacuation
• Two cutting edges for clean holes
• Shank with 3 flats for secure clamping

Faster holemaking with fewer tool changes

The 4–12 mm stepped design enables continuous enlargement of holes without frequent tool swaps, increasing throughput in repetitive drilling tasks. Constructed from HSS, the bit preserves sharpness under typical workshop loads while the two cutting edges and cross-ground tip assist fast entry and a centred start. This combination converts tool capability into measurable efficiency: fewer interruptions, reduced set-up time and more consistent hole diameters, which translates into smoother production processes and predictable cycle times.

Secure clamping and superior chip control for cleaner results

A shank with 3 flats and a shank length of 22 mm ensure stable fixation in chucks or holders, limiting slippage and run-out during operation. The spiral flute improves chip evacuation compared with straight-fluted variants, reducing clogging and heat build-up at the cutting zone. The specified 118° point angle and 90° step angle promote precise centring and controlled material removal at each step, producing cleaner edges and minimising burring—benefits that support downstream processes and reduce rework.

Precision execution and straightforward integration into the workshop

Made as a precision item with nine progressive steps, this tool delivers repeatable step diameters and predictable hole profiles. The design supports a streamlined tooling strategy: one drill covers multiple diameters, easing inventory complexity. Technical maintenance is simple thanks to the robust HSS body and conventional geometry; the clear construction makes inspection straightforward and helps planners forecast replacement intervals. For quality-focused operations, the bit provides the reliability expected from professional tooling and facilitates smoother throughput in mixed-batch environments.

FAQ

What diameters does this step drill cover?
The TECWERK step drill bit covers a continuous range from 4–12 mm, enabling stepped hole enlargement without changing tools.

How many steps are on the bit and what does that mean?
The tool has 9 steps, which provides a sequence of incremental diameters allowing progressive drilling from the smallest to the largest size in the specified range.

What advantages does the spiral flute provide?
The spiral flute improves chip evacuation compared with straight flutes, helping to reduce clogging and heat at the cutting edge during drilling.

How does the shank design affect clamping?
The shank with 3 flats increases grip security in the chuck or holder, reducing slippage and run-out for more consistent hole quality with the TECWERK step drill.

What is the purpose of the cross-ground tip and 118° point angle?
The cross-ground tip and 118° point angle aid in centring and initial penetration, promoting accurate starts and minimising wandering on contact with the workpiece.
