The drill arm is an artificial body part that provides both the functionality of a normal arm, while also increasing Mining Speed by 160%, Deep Drilling Speed by 70%, and inflicting a -8% Moving penalty.

Acquisition

Drill arms can be crafted at a Machining table once the Specialized limbs research project has been completed. They require 60 Steel, 8 Components, 15,000 ticks (4.17 mins) of work and a Crafting skill of 5.

They can also be bought from Outlanders and Empire settlements, and are occasionally found installed on raiders.

Summary

Body part

Drill arms replace the user's organic arm. Note that unlike every other artificial arm in the game, this part does not attach to the shoulder but instead the arm itself. This means that certain body part destructions can prevent its attachment and that the drill arm cannot be used after an artificial arm has been attached to that side. It is unknown whether this is a bug. They are universal and can be installed on either the left or right. The drill arm has a part efficiency of 100%. This fully replaces the functionality of a normal arm but provides no enhancement - when coupled with the arm body part having a Manipulation importance of 50%, it results in an increase in manipulation of up to 50% when replacing a missing or totally inoperable hand or arm. Manipulation, in turn, affects a great many stats. For a full list of affected stats, see Manipulation.

Other effects

Each drill arm also provides +160% Mining Speed and a +70% Deep Drilling Speed. The effects of two installed arms stack. These bonuses apply as offsets to the base value of the stat, and are then multiplied by Global Work Speed, Skill factors and Capacity factors meaning the final increase from installing a drill arm can be significantly more than the nominal values. See those pages for details.

Each drill arm also inflicts a −8% Moving penalty. Moving, in turn, affects the following stats: Hunting Stealth, Melee Dodge Chance, Move Speed. This results in a directly proportional change to a pawn's move speed, and a improvement in melee dodge chance equivalent to an losing −1.44 levels of Melee skill per arm replaced.

Combat

A drill arm replaces the natural "Fist" attack of the replaced arm with a more powerful Stab attack.

	Drill arm	13		20%	Stab

Installation

Installing the part requires 2,500 ticks (41.67 secs) of work, ?x medicine of ?? quality or better, and a Medical skill of 4.

Removing the part requires ? of work, ?x medicine of ?? quality or better, and a Medical skill of ?.

If the operation fails, the part has a chance^{[What Chance?]} to be destroyed.

Analysis

Deep drills offer an absurd boost to mining speed. With 1 drill arm, a Mining 0 pawn mines as fast as a baseline Mining 13 pawn, and drills as fast as a Mining 7 pawn. While the drill arm disables the use of a work-enhancing bionic arm or archotech arm, if a pawn's primary job is to mine, then the drill arm offers a clear benefit. (Note that this implant does not increase Mining Yield, so your Mining 0 pawns won't get much out of any ores they mine.)

The increased mining speed can be very helpful to your colony. A fast miner can easily construct a huge mountain base. Deep drills in particular are slow to operate, so a drill arm can expiate expansion in the late-game. You might even want 2 drill arms for your dedicated miners.

This comes at a cost of movement speed. In addition to the reduced efficiency in regards to day-to-day work, installing a drill arm will hinder a pawn's performance in combat. For ranged fighters, slower movement means that kiting tactics are no longer as viable. For melee fighters, the Moving penalty directly encumbers a pawn's melee dodge chance. This can be eventually compensated, partially, by using bionic legs.

Drill arms can also be used as a viable replacement for an destroyed or dysfunctional arm. There are no wooden arm replacements, and prosthetic arms are only 50% as effective as a regular arm, resulting in −25% Manipulation per arm. For comparison, the drill arm offers full Manipulation in exchange for −8% Moving, in addition to the benefits of mining.
