Drill Hand Remer
- Drill Remer
- A reamer is a type of rotary cutting tool used in metalworking
- Reamed holes are used to create holes of precise circularity and size
- Flute Geometry – 7º Helix Left-hand spiral.
- Weight – 200g
- Colour – Light Silver
- Hand reamers have a square on the end of the shank which allows placement into a wrench which the user rotates by hand.
- Used for opening out and finishing existing holes to H7 tolerance in most ferrous and non-ferrous metals.
- Flute Geometry – 7º Helix Left hand spiral.
- To obtain the best results when using reamers it is essential to make them work. It is a common fault to prepare holes for reaming with too little stock left in. If insufficient stock is left in the hole before reaming then the reamer will rub quickly, show wear and will result in loss of diameter. It is equally important for performance not to leave too much stock in the hole.
- A hand reamer has a longer taper or lead in at the front than a machine reamer. This is to compensate for the difficulty of starting a hole by hand power alone. It also allows the reamer to start straight and reduce the risk of breakage. The flutes may be straight or spiral.
USAGE & ADVANTAGES:
- Once you have part of the taper formed.
- You can check the taper angle by marking a good taper with marking pen and slipping it into the partial taper and giving a rotation.
- It also allows the reamer to start straight and reduce the risk of breakage.
- The flutes may be straight or spiral.
