Mortar Rake Bits & Raking Pins

6 products

Mortar rake drill bits (router pins) for M14 angle grinders: diamond for hard cement mortar, carbide for soft lime. Where a raking blade cuts a straight bed joint, a rake bit goes where the blade cannot: perp ends, vertical joints, corners and the detail around openings. Most repointing jobs need both.

Every rake bit here threads straight onto a 115mm or 125mm angle grinder (M14). The 8 x 100mm long-reach pins also work as a brick removal tool when you need to take out a single brick.

More about this range

Where a raking blade cuts a straight bed joint fast, a rake bit goes where the blade cannot - perp ends, vertical joints, corners and detail around openings. Most repointing jobs need both.

Why a rake bit rather than a blade

  • Routes both directions - horizontal bed joints and vertical perps with the same tool.
  • M14 fitting - threads straight onto the spindle of any standard angle grinder.
  • Controlled depth - easier to hold a consistent rake depth in irregular or historic brickwork.
  • Diamond tipped - far longer life than tungsten in hard cement mortar.

What we stock

The diamond mortar rake pin is the standard M14 rake for grinder work. For lime and softer historic mortar, the DR850 joint rake and the TR350 repointing tool cut with less risk to the brick face. The starter kit and repointing kit pair a rake with a depth-adjustable dust guard.

Extraction is not optional

Routing mortar throws a concentrated plume of respirable crystalline silica straight back at the operator. Fit a dust extraction guard to an M-class vacuum - it is a legal duty on site, and it keeps the joint line visible while you work.

Raking long horizontal runs instead? A mortar raking blade is faster. See all mortar rake tools, or read how to repoint brickwork.
