A 118 degree angle is ideal for drill bits, but you will need to create a 59 degree angle on your jig to get achieve this angle. Re: 118 or 135 Degree Drill Bits Post by David_Brown » Sun Jan 05, 2003 4:30 am Point angles are commonly 118 degrees, except for high speed steels, 118 to 135 degrees, aluminum alloys, 90 degrees to 140 degrees and magnesium alloys, 70 to 118 degrees. Bits with steeper points, such as those with 118-degree angles, are suited for softer material. GHURING might have some info if they have a web site. 90-degree bits are only used for soft materials such as plastic and aluminum, they get dull very fast. Usually see 118 degrees or even 90 degrees recommended. While you can drill a hole with almost any drill point, the one you use may not be the best for the whole job, whether you are drilling one hole, a hundred holes, or thousands! Easy online ordering for the ones who get it done along with 24/7 customer service, free technical support & more. The selection of an appropriate drill point angle for your bit should be informed by questions about your application. A 135° drill is flatter than 118°, which means that more of its cutting lips engage with the material surface sooner to begin the full metal cutting action. Harder materials, such as stainless steel or titanium, will require a flatter, heavy duty drill bit, such as a 135° split-point bit. General purpose taper shank drill bits. I used to work as a drill press operator and drill grinder for Allis Chalmers. 118 degree less aggressive angle suitable for drilling softer materials. Which Drill Point Angle Should I be Using? A lot of problems in drilling are related to the web of the drill. Check out our guide below for what angles are optimal based on the material that is being drilled: There are a number of drill point configurations and these may be found in both 118° and 135° variants. Material applications: alloyed steel, tool steel, carbon steel, and cast iron. #1 - #30 drill bits have a 135° split point tip and #31 - #60 drill bits have a 118&deg: tip. by JeffinWI » Sun Jan 05, 2003 12:47 am, Post Also, make sure that the the bit touched the drill stop in the alignment port and the clamps have grasped onto the narrowest part of the drill, be sure to tighten the bit securely … Holes in these bits allow coolant to be run through the tool for more efficient chip evacuation. 118° 120° 130° 135 ... Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other bits. Now the same processes are used for special drills and end mills so we can provide the fastest delivery possible. There is an exhaustive discussion about drills at this site, Favorite Places to Visit In Your Area & Upcoming Events, Site Software Q&A and Maintenance Notices, http://newmantools.com/machines/drillpoint.html. A 118° drill bit angle is common on general purpose drill bits used for drilling a range of materials, such as wood, aluminum, and plastic. by Rich_Carlstedt » Tue Jan 07, 2003 11:31 pm, Post Over time, tool makers learned that by grinding a conical point with a flat surface (a facet) to create a linear chisel, they could reduce the thrust required and also improve the process of cutting the metal or wood and removing the chips. Point angle is the angle of the cutting head on the tip of the bit. by David_Brown » Sat Jan 04, 2003 11:30 pm, Post Choose your Quantity and click "add to cart" 3. 1 in Max. If I have to do many holes, then I would look to grind the bit to optimize it for the job. The 118° tips are for general purpose drilling. There are three commonly used angles in consumer drill bits: 90-degrees, 118-degrees, and 135-degrees. The AXIS Point™ starts 10X faster. Industrial & Scientific. In addition to the drill point angle, factors that can affect successful drilling include: There are two main characteristics that define a drill point. Click the Arrow next to the Drill Bit Size field to select drill size 2. The most common included angles for drills are 118° and 135°.

Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. It took about 1 hour and 15 mins in total. First is the included angle of the point and the second is the configuration of the point. 1/8" drills 10" long with a conventional point have been known to bend to the point of looking like a jump rope [img]/ubb/images/graemlins/shocked.gif"%20alt="[/img] Now THAT, will get your attention!

I resharpened some 34 drill bits from 3/32" to 1/2" that were blunt and changed one from 118 degrees to 135 with a split point. Split points, more accurately web thinning, were put on by hand as SOP. Plastic? The split point reduces the torque on the drill...it doesn't have to "plow" a bunch of metal to each side so it can get in front of the cutting edge like a "regular" drill point. The 118° tip bits are for general purpose use. Not only do they require 50% less thrust, but they also generate 60% less heat than a conventional drill point. How about standard or split point?
