Cutting head for a reamer

A cutting head (10) of a reamer having an axis of rotation (A) defining a forward-to-rear direction and comprising:

• a cutting head forward end (14), a cutting head rear end (16) distal the cutting head forward end (14) and a peripheral surface (18) therebetween, the peripheral surface (18) comprising at least two wiping pads (22) extending rearwardly from the cutting head forward end (14), the peripheral surface (18) between two adjacent wiping pads forming a peripheral section (58), and
• at least one cutting section (20) located adjacent the cutting head forward end (14) comprising:
• a cutting edge (30) extending from the cutting head forward end (14) in a rearward and radially outward direction to the peripheral surface (18), the cutting edge being formed at an intersection of a rake surface (32) and a relief surface (34), the rake surface (32) being generally tangentially directed, facing a direction of rotation (B) and having a rake surface first end (40) that is distal from the cutting edge (30),
• a deflecting surface (38) adjacent the rake surface (32) and generally transverse thereto, the deflecting surface (38) extending from the rake surface first end (40) in a direction away from the cutting edge (30), wherein:
• the deflecting surface (38) makes an acute axial angle (α) with respect to the axis of rotation (A) such that an imaginary extension of the deflecting surface (38) intersects the axis of rotation (A) at a point forward of the cutting head, and
• a rear end (41) of the deflecting surface (38) joins the peripheral surface (18) adjacent the cutting section (20) and distal the rear end (16) of the cutting head (10).
