Difference Between Drilling, Boring & Reaming - .

27.07.2017· The main difference between drilling, boring and reaming is that drilling is when you make a brand new hole in your work piece. But boring is when you enlarge the hole. When you give a finishing touch to your hole that means you are reaming. Giving a finishing touch to the hole means making the hole smoother. Next thing about the three processes is that they have individual tools for .

Difference Between Drilling, Boring and Reaming

Differences between drilling, boring and reaming. Purpose of operation. Drilling is carried out to originate a cylindrical hole. So it can create a hole on a solid surface. Boring is performed to enlarge an existing hole or to convert a cylindrical hole into a taper hole. Reaming is carried out to highly finish the surfaces of a hole. Its purpose is to improve dimensional accuracy and ...

Back Reaming | 2001-05-31 | National Driller

Back reaming is a part of almost every horizontal directional drilling (HDD) operation. I say "almost every" because there are times when the operator is installing small cable that simply involves pulling the product back through a hole that is already considerably larger than the outside diameter (OD) of the cable. But, by and large, HDD involves the process of drilling a pilot hole; taking ...

Cutting Speeds & RPM Calculations

Although you will find specific cutting speeds for reaming, a simple rule of half the speed will work for most reaming operations. Using half the spindle speed you calculated for the drilling operation is a commonly accepted method for determining the reaming speed in most machine shops. Let's try an example. A high speed steel "G" drill is being used prior to reaming a 3/8 hole on a piece ...

Getting reaming right | Cutting Tool Engineering

01.06.2010· When too much stock remains for reaming after drilling, end users have the option of reaming twice. Monster Tool's Lynberg suggests first applying a smaller reamer followed by a reamer of the required size. "Drilling to open up a hole usually causes drill failure due to unequal and uneven stress along the drill's cutting edge and is not recommended," he said. Lynberg added that plunge ...
