Select the Feeds and Speeds tab and specify the feedrates and spindle speeds for the operation.You can specify a machining feedrate for the boring phase of the operation and a chamfering feedrate for the chamfering phase. Similarly, you can specify a machining spindle speed for the boring phase and a smaller spindle speed for the chamfering phase.

Cobalt – Cobalt bits are a special formulation of high speed steel with cobalt added in to withstand very high drilling temperatures. Cobalt bits are specifically designed for drilling very hard, abrasive materials such as treated stainless steel, titanium and cast iron. Cobalt bits are not designed for general purpose use.  Vermont American cobalt drill bits feature the following: (1) grip tight shank for positive chuck hold, (2) cobalt withstands high drilling heat for longer bit life and includes thick web for increased durability and (3) 135 degree split point starts fast and reduces drill walking.  Click here to see available sizes.

The Boring and Chamfering dialog box appears directly at the Geometry tab . This tab includes a sensitive icon to help you specify the geometry. Areas of the icon are colored red indicating that this geometry is required.

Titanium – High speed steel bits which have been coated with titanium nitride. This special coating gives the bits a very high surface hardness to help penetrate tough materials, makes the bits highly corrosion resistant and significantly reduces friction between bit and workpiece. Titanium coated bits last up to 6X longer than standard high speed steel bits.  Vermont American titanium drill bits feature the following:  (1) grip tight shank for positive chuck hold, (2) titanium coating hardens bit surface or improved durability in tough, repetitive applications and acts as lubricant, requiring less torque and less heat build-up for longer bit life, (3) speed helix augers dust away from tip more quickly, reducing heat for long life and (4) 135 degree split point starts fast and reduces drill walking.  Click here to see available sizes.

Select the Strategy tab and specify the following parameters:Approach clearance (A) and Approach clearance 2 (A2) Depth mode: By shoulder (Ds)Note: The depth value used is the one specified in the Geometry tab. Breakthrough (B) Dwell in seconds First compensation number depending on those available on the tool for top chamfering Second compensation number depending on those available on the tool for bottom chamfering. If a Plunge mode is selected (By Tip or By Diameter), deselect the Plunge for chamfering check box to deactivate the plunge motion for the chamfering phase of the operation, if needed. In this case, the plunge motion is done for the boring phase only. Note: In the tool path represented in the Strategy tab, tool motion is as follows.Boring phase: Motion at machining feedrate from 1 up to the position where hole is to be bored Possibly, activation of second tool compensation number Rapid feedrate up to a clearance position before start of chamfering. Chamfering phase: Motion at chamfering feedrate from clearance position to 2 Dwell for specified duration Possibly, activation of first tool compensation number Retract at retract feedrate from 2 to 3.

118° Point – Designed primarily for drilling into wood or plastic. Center punch is required for drilling into metal, otherwise bit will “walk” or “skate”.

High Speed Steel (HSS) – Standard general purpose bits with a polished finish with silver appearance.  Click here to see available sizes.

The tool path is computed. A progress indicator is displayed. You can cancel the tool path computation at any moment before 100% completion.

Select the Macro tab and add approach and retract motions to the operation. See Defining Macros on Axial Machining Operations

Speed Helix – More aggressive drilling angle on drill bit flutes, which provides up to 3x faster penetration.  Extends the life of the drill and extends battery life in cordless drills.

Activate the Manufacturing Program and click Boring and Chamfering in the Axial Machining Operations toolbar. You can create a Boring and Chamfering operation. A Boring and Chamfering entity is added to the Manufacturing Program.The Boring and Chamfering dialog box appears directly at the Geometry tab . This tab includes a sensitive icon to help you specify the geometry. Areas of the icon are colored red indicating that this geometry is required.

135° Split Point – Starts on contact in metal, wood and plastic. Eliminates “walking” or “skating” when drilling into metal. 135° Split Point on all bits above 1/8″.
