Cutting tool having a coolant chamber with an integrally formed coolant deflection portion and tool body

A cutting tool (20) having a central tool axis (A) extending in a forward direction (DF) to a rearward direction (DR), the cutting tool comprising:

• a tool body (24) comprising a tool body surface (26) and an insert pocket (28) recessed therein;
• and
• a cutting insert (22) releasably retained in the insert pocket (28), wherein:
• the tool body (24) comprises:
• a coolant chamber (44) that opens out to the tool body surface (26) at a coolant chamber opening (46);
• at least one coolant duct (60a, 60b) that opens out at an outlet orifice (56) in the coolant chamber (44);
• the coolant chamber (44) is bounded on a side opposite the outlet orifice (56) by a coolant deflection portion (58) that is integrally formed with the tool body (24) in a unitary one-piece construction;
• and
• in a front view of the coolant chamber (44), the outlet orifice (56) is at least partially hidden by the coolant deflection portion (58).

A tool body (24) comprising a tool body surface (26) and an insert pocket (28) for seating of a cutting insert (22), recessed therein;

• wherein:
• the tool body (24) comprises:
• a coolant chamber (44) that opens out to the tool body surface (26) at a coolant chamber opening (46);
• and
• at least one coolant duct (60a, 60b) that opens out at an outlet orifice (56) in the coolant chamber (44);
• wherein:
• the coolant chamber (44) is bounded on a side opposite the outlet orifice (56) by a coolant deflection portion (58) that is integrally formed with the tool body (24) in a unitary one-piece construction and at least partially overhangs the outlet orifice (56) in a direction towards the insert pocket (28).
