Twist Drilling vs Annular Cutting - A Primer

Twist Drilling vs. Annular Cutting – A Primer
by Tom Carroll, CS Unitec Portable drilling in applications such as construction, steel fabrication and more poses many challenges - the method of hole creation is just one of them. Understanding the difference between twist drilling and annular cutting, and the equipment, power and time required, will have you efficiently and expertly cutting holes in steel, stainless steel and other metals.
The Methods: Annular cutting, the cutting of metal with a hollow-core bit, is an efficient way to create holes 7/16" to 5" diameter (up to 3" deep) with an accuracy of +0.004", -0.000" in steel, stainless steel, etc. Multiple cutting teeth cut only the material around the periphery of the hole, forming a solid metal slug. In fact, the wall thickness of the cutter is approximately 1/4" thick, meaning that no matter what size hole you are cutting, you are only removing a small amount of material around the edge of the hole. Because the cutting surface of annular cutters is spread out over multiple cutting edges (teeth), they remain sharper longer and can create 5 to 10 times more holes than traditional twist drills. Final holes are smooth and burr-free - no reaming is required. Additionally, hole cutting with annular cutters requires no predrilling or stepdrilling. Annular cutters are commonly used to do on-site repair and to make mechanical openings and pipe thru holes. The annular cutter creates the hole in a 3-step process: 1. The pilot pin accurately centers the cutter over the area to be drilled. 2. During drilling, the pilot pin retracts and allows the internal lubrication to reach the cutting teeth. 3. When the hole is complete, the slug is automatically ejected from the cutter, leaving an accurate, finished hole. Another unique feature of annular cutters is their tapered inner wall. On high-quality precision-engineered cutters, the tapered wall design serves two functions. Primarily, it accommodates for the effect of frictional heat, which causes the expansion of both the cutter and the internal metal slug (coupon). Secondly, it facilitates the smooth, easy ejection of the slug. When preparing to drill holes on-site or in the shop, it is important to consider the method of drilling as well as the equipment, power and time required to complete the project. These factors will help you determine the best method to complete your hole-making project.

Gas Mixture Calculation Chart
Monday, July 21, 2014 3:10:35 PM America/New_York
How to mix gas and calculate volumes :
How to figure out mix ratios: Ok you got some number like 30:1 or 50:1 or whatever and you want to know how much oil to mix in the amount of gas you have... first need like units ie.. gallons (gal) and gallons or ounces (oz) and ounces. Normally gas is in gallons and 2 cycle oil is in ounces so we need to convert one to the other ... just convert gallons to ounces.
There are 128 oz in a gallon. - trust me!!.
128 oz of gas mixed 50:1 = 128oz / 50 parts = 2.56oz Yes when you add in the oil there will be 51 total parts this is not a problem you are using a mix ratio Ie. mix 50 cups of gas with 1 cup of oil ... or ... 50:1 ... Ok ???
Don't over analyze this: The engineers of the motor's for our weed wackers tried to make it easy on us, so any redneck could have a long career in the mowing business ... ok.
Or for the math people ... Where
G = Gallon(s) of gas you have.
M = Mix Constant (ie 50 if you are using 50:1)
G * 128
------- = oz's of oil to add
M
If you are still confused just use the chart below... find how much gas you got on top and your ratio on the side and meet them to find the amount of oil you will need. "In ounces (oz)"
Gal/mix | 0.5 | 1.0 | 1.5 | 2.0 | 2.5 | 3.0 | 5.0 | 10.0 |
---|---|---|---|---|---|---|---|---|
20:1 | 3.20 | 6.40 | 9.60 | 12.80 | 16.00 | 22.40 | 32.00 | 64.00 |
25:1 | 2.56 | 5.12 | 7.68 | 10.24 | 12.80 | 15.36 | 25.60 | 51.20 |
30:1 | 2.13 | 4.26 | 6.39 | 8.53 | 10.66 | 12.80 | 21.33 | 42.66 |
35:1 | 1.82 | 3.65 | 5.48 | 7.31 | 9.14 | 10.97 | 18.28 | 36.57 |
40:1 | 1.60 | 3.20 | 4.80 | 6.40 | 8.00 | 9.60 | 16.00 | 32.00 |
50:1 | 1.28 | 2.56 | 3.84 | 5.12 | 6.40 | 7.68 | 12.80 | 25.60 |
100:1 | 0.64 | 1.28 | 1.92 | 2.56 | 3.20 | 3.84 | 6.4 | 12.8 |

Core Drilling thru Precast Concrete Plank
Tuesday, May 30, 2017 4:08:27 PM America/New_York
Core drilling precast concrete plank would follow the same procedures as with drilling a regular hole except you would use diamond core drill bits made especially for cutting thru the precast panels. Remember that precast plank is a structural system and it is recommended that you consult with an engineer on your project before core drilling.
