# Overview

# Applications

This high-quality, easy-to-handle pneumatic Positive Feed Drill (PFD) can be used for drilling holes in various metals and composites.

# Main components and functions

Pos | Part | Function
--- | --- | ---
1 | Spindle | Main rotating part of the drill.
2 | Spindle guard | Protects the operator from the rotating spindle. Provides the drill with coolant to the drill bit.
3 | Head | Transfers rotational torque and feed from the motor to the spindle.
4 | Feed cassette | Defines spindle feed rate. Measured in inches per revolution (IPR) or millimeters per revolution (mm/rev).
5 | Air logic | Operates the drill.
6 | Split gear | Defines rotational speed. Measured in revolutions per minute (RPM).
7 | Range gear | Defines RPM range.
8 | Vane motor | Supplies power and rotation to the spindle.
9 | Motor valve | Supplies the airflow to the vane motor and the emergency stop button.
10 | Start | Starts the motor and activates drill feed and rotation mechanism. The motor continues to run after the button is released. When spindle reaches the pre-defined drilling depth, it returns automatically to the starting position.
11 | Rapid advance (optional) | Activates rapid spindle feed. The spindle advances to the work surface faster than the regular feed rate but does not rotate. Releasing the button stops the spindle.
12 | Retract | Returns the spindle to the starting position at any time during drilling cycle. The motor switches off automatically after retract.
13 | Emergency stop | Switches off the motor, and stops the spindle at any time during drilling cycle. Once pressed, the emergency stop button locks in position. You must manually reset the emergency stop to restart the drill.

# Starting position and drilling depth

Using stop rings, you can define the following parameters:

- Starting position of the drill bit

- Drilling depth

Pos | Part | Function
--- | --- | ---
1 | Starting position ring | Defines the starting position for drilling. This allows for quick positioning of the drill bit at the pre-defined safe distance to the surface. The starting position can be adjusted.
2 | Depth ring | Defines the drilling depth.
3 | Depth valve | Controls the drilling depth. Once the depth ring reaches the valve, it activates the valve, and the spindle retracts into the starting position. The motor automatically switches off after retract.
4 | Starting position valve | Controls the starting position for drilling. Once the starting position ring reaches the valve, it activates the valve that switches off the motor.

You can calculate the distance between the depth ring and the drill head (dimension L in the figure below) for the desired drill depth D according to the following formula:

L (mm) =D (mm) – 31.0 mm

L (in) = D (in) – 1.2 in

# Speed

The combination of range and split gears determines the speed of the drill spindle. Make a selection from the available combinations of range and split gears in the table below to get the desired RPM.

| Range gear |
--- | --- | ---
RPM | Ordering No. | Split gear ratio
38 | 4141 0043 95 | Low
50 | 4141 0043 95 | 1:1
67 | 4141 0043 95 | High
100 | 4141 0043 92 | Low
140 | 4141 0043 92 | 1:1
180 | 4141 0043 92 | High
200 | 4141 0043 90 | Low
270 | 4141 0043 90 | 1:1
360 | 4141 0043 90 | High
400 | 4141 0043 94 | Low
530 | 4141 0043 94 | 1:1
700 | 4141 0043 94 | High
670 | 4141 0043 93 | Low
900 | 4141 0043 93 | 1:1
1200 | 4141 0043 93 | High
1330 | 4141 0043 91 | Low
1770 | 4141 0043 91 | 1:1
2360 | 4141 0043 91 | High

A split gear ratio can be set to high, 1:1 or low depending on the position of the shaft (1) in the relation to the indent (2), see the figure below. Markings on the split gear housing indicate ratios corresponding to shaft positions.

Secure that the shaft is in the right position with the fork-shaped tool (4141 1114 00). See the figure below.

# Velocity rapid advance – PFD1500RA-R (only for models with rapid advance)

The rapid advance is depending on the feed rate. High feed rate generates high rapid advance and vice versa.

Model | Spindle (rpm) | Velocity rapid advance (mm/s), ±10% | Velocity rapid advance (inch/s), ±10%
