Mechanical pencil with rotating lead engine

The uni-ball Kuru Toga Elite 70137 is a refillable mechanical pencil built for students and professionals who need consistently sharp lines. Its 0.5 mm nano-diamond lead advances automatically as you write, keeping the tip pointed for detailed notes, diagrams and everyday drafting tasks.

0.5 mm lead diameter for fine detail

The single specification that determines fit is the 0.5 mm lead size, which produces narrow, precise marks suited to small handwriting and technical sketches. Writers who require a broader stroke or a different hardness grade will find this model does not meet that need.

Diamond-infused lead resists breakage under pressure

The extra-durable, diamond-infused #2 HB lead maintains darkness and strength during long writing sessions, reducing the frequency of lead snaps. A replaceable eraser allows quick corrections without interrupting workflow, so the pencil stays reliable through extended use.

Questions about this item

How does the 0.5mm rotating lead engine affect everyday writing?

The Kuru Toga mechanism rotates the lead incrementally as you write, keeping the tip consistently sharp for uniform 0.5mm lines without frequent manual adjustment.

What lead standard does the 0.5mm size follow for refills?

It uses standard 0.5mm diameter leads, commonly graded HB or #2, so compatible refills are widely available from multiple brands.

Will the 19.1cm length and 7.1cm width fit a standard pen loop or case?

At 19.1cm long and 7.1cm wide with the clip, the silver barrel fits most standard pen loops, pocket clips, and pencil cases designed for full-size mechanical pencils.
